c Minimum: approximately 3 images are used for the analysis.

c Normal: approximately 6 images are used for the analysis.

c Superior: approximately 8 images are used for the analysis.

c Maximum: approximately 11 images are used for the analysis.

The precision names may appear differently if the system has been upgraded from a previous version to Software version 2.3.2. In the case of a system that has been upgraded to version 2.3.2, the precision levels may be called ‘Low’ (corresponding to ‘Minimum’), ‘Medium’ (corresponding to ‘Normal’), ‘High’ (corresponding to ‘Superior’) and ‘Very High’ (corresponding to ‘Maximum’).

4 Select the Cell Type that optimally recognizes your cells from the Cell Type list. The following Cell Types are available by default:

c Min. Size for small cells with a diameter of about 6 µm, such as lymphocytes; default sedimentation time is 90 seconds.

c Std. Size for normal sized cells with a diameter of about 12 µm, such as HB58; default sedimentation time is 60 seconds.

c Max. Size for large cells of more than 16 µm, such as K-562; default sedimentation time is 60 seconds.

If a new Cell Type has been created, it can also be selected from the same ‘Cell Type’ drop-down list.

Do not select the Cell Type option Illumination Test, if it is available. This Cell Type is designed for service purposes only and is not intended for analysis of cells. The parameters for this Cell Type should not be changed!

The sample is injected into the chamber, and the cells are allowed to settle to the bottom of the flow chamber for a specified amount of time (the sedimentation phase). The system checks the flow chamber for impurities with a separate scan (Prescan) during the sedimentation phase.

If the system detects impurities in the flow chamber, an error message, “Dirt or bubbles detected during Prescan!” appears. The measurement is completed and results calculated even if this error message appears. If the error message appears, check the Prescan image at the end of the measurement (see Viewing the Prescan Image in the Cedex HiRes Analyzer Operator’s Guide). If the flow chamber appears to have dirt or impurities, perform a Standard Clean before performing a new measurement (see Carrying out a Cleaning Routine in the Cedex HiRes Analyzer Operator’s Guide).

Measurement of up to 20 samples in a row leads to prolonged incubation (up to 90 minutes) of cells at room temperature. Tests using several different cell lines (CHO-K1 and several hybridoma cell lines) showed no noteworthy influence of the prolonged incubation times on the measurement results. However, this result may not apply to all cell lines. Roche recommends testing especially sensitive cell lines in advance to deter-mine the number of samples that can be measured in a row without affecting the cells.

1.1 Performing Measurements for Growth Curve Analysis

1 Immediately after subculturing the cell culture of interest, remove a sample and perform a full analysis with regard to cell concentration and viability using the Cedex HiRes Analyzer as described in Section B Main Application: Counting Cells and Determining Viability.

2 Measure the cell culture with regard to cell concentration and viability at regular intervals for 7 to 10 days. Intervals between measurements should typically range between 18 and 28 hours.

3 Approximately 2 or 3 days after the cell culture has stopped increasing in viable cell concentration, the culture can be discarded and a growth curve analysis prepared as described in the following section.

n

Many cell cultures reach their growth limits within 7 to 10 days after being subcultured, particularly if there is no exchange of media or addition of nutrients during that time. However, the time needed for a cell culture to reach maximum growth and either decline in cell concentration or reach senescence (the plateau phase of a growth curve) can vary depending on the cell type and conditions in which the culture is cultivated.

1.2 Result AnalysisAfter all measurements have been carried out as described above, prepare the Cultivation Time Chart (CTC) for the analysis of measurement results and cell culture growth pattern as described in the following chapters:

1) Create a CTC View

2) Add One or More Series of Measurements to the CTC View

1.2.4 Work with the Exponential Regression Function to Determine the Specific Growth Rate and Doubling Time of the Cell Culture Based on the Log Phase of Growth

Specific growth rate and doubling time for a cell culture are generally calculated based on the change in viable cell concentration during the log phase of growth only. This is the part of the growth curve during which the cell culture grows at its quickest. Since the calculations for specific growth rate and doubling time should only be carried out using measurement results from the log phase, the measurement results from the lag and plateau phases need to be removed from the chart before the calculations are performed.

Determine the Specific Growth Rate and Doubling Time of a Culture Based on The Log Phase of the Growth Curve

1 In the CTC Views dialog box, select the View to be used for the analysis of specific growth rate and doubling time.

2 Click on the VIEW CHART button.

The Cultivation Time Chart dialog box is displayed showing the change over time in the viable cell concentration of the cell culture.

3 Study the curve to determine which points on the curve belong to the log phase of growth.

In the figure below , for example, the first three points are most likely part of the lag phase, while the last three points are most likely part of the plateau phase. These points will need to be deactivated before the specific growth rate and doubling time can be calculated.

1.2.5 Checking Regression Curve Fitting

If the regression curve does not fit well to the measurement results for viable cell concentration, the specific growth rate and doubling time will not be as expected for the culture. See figure below:

The measurement results for viable cell concentration should fit relatively closely to the regression curve determined for the measurements in the Exponential Regression chart. In the case shown above, measurement results from samples of the cell culture when it was in the lag and plateau phase were included in the Cultivation Time Chart and Cultivation Time Chart - Exponential Regression chart. Therefore, the fit and calculated doubling time is not as expected for the culture.

Perform the following steps:

1 Check the curve for viable cell concentration in the Cultivation Time Chart.

2 Temporarily remove measurement points that are not part of the log phase of growth, using the Use checkbox in the Selection of Data Series dialog box.

2 Analyzing Unusual Cells

2.1 OverviewThe image analysis Operator is the part of the software that takes care of the image evaluation. For various application scenarios, Roche has put in three pre-settings for the Operator that have been adapted to a wide cell size spectrum:

c Min. Size for small cells with a diameter of about 6 μm, such as lymphocytes; default sedimentation time is 90 seconds.

c Std. Size for normal-sized cells with a diameter of about 12 μm, such as HB58; default sedimentation time is 60 seconds.

c Max. Size for large cells of more than 16 μm, such as K-562; default sedimentation time is 60 seconds.

The Cell Types may have slightly different names if the system has been upgraded from some previous version to Software version 2.3.2.

Individual adjustments of the operator can be helpful or necessary for cell cultures that, for instance, have an unusual optical appearance, or for a counting strategy that deviates from the standard counting strategy (e.g., counting aggregates differently).

Adjustment of the Operator is referred to as creating a new Cell Type. A new Cell Type can be created, or an already existing Cell Type can be readjusted. This is done using a number of parameters that influence the way in which an image is evaluated. Each of these parameters directly influences the image processing strategy and, hence, the measurement results.

Once a new Cell Type has been created and modified, measurements can be carried out with the new Cell Type, and existing measurements can be reprocessed with the new Cell Type.

The parameters of the factory-installed presets are over writable. For data safety reasons, the parameters of the factory-installed presets should not be altered.

2.2 Example of Cells Not Recognized by the Cell Type Std. SizeIn the image from a measurement, shown below, some live and dead cells were not identified using the standard Cell Type Std. Size. This particular culture, therefore, requires a new Cell Type that includes changes to certain parameters in the image analysis Software (Operator). The following chapters describe the steps to create a new Cell Type, adjust the parameters for the Cell Type, and reanalyze the images using the new Cell Type:

1) Create a New Cell Type

2) Modify the Parameters for the New Cell Type via the Live Operator dialog box

3) Reprocess the Measurement Using the New Cell Type as the Basis for the Image Analysis

2.2.1 Create a New Cell Type

To create and save a new Cell Type:

1 Open the Cell Type List dialog box by selecting the Cell Type List option in the Master Data menu.

There are several options in this dialog box, including:

c NEW: Create new Cell Types

c EDIT: Modify existing Cell Types

c VIEW: View existing Cell Types

c DELETE: Delete existing Cell Types

c LIVE OPERATOR: Open the Live Operator dialog box

2 Select the existing Cell Type on which the new Cell Type should be based, and click on the NEW button.

Do not select the Cell Type option Illumination Test, if it is available. This Cell Type is designed for ser-vice purposes only and is not intended for analysis of cells. The parameters for this Cell Type should not be changed!

3 A message will be displayed asking if the new Cell Type should be based on the highlighted Cell Type in the list. Click on YES.

The Cell Type dialog box will open:

CC

4 Fill in the information for:

c The name of the new Cell Type Sample preparation procedure.

c Focus Offset: the offset from the ideal focus point.

The Focus Offset should be set to -25 to ensure best results for cell count and determination of viability. Please consult the local Roche Technical Service before using any other number for the Focus Offset as selecting another value for this parameter may lead to poor results.

c Sedimentation Duration: the amount of time the cells are allowed to settle before chamber is scanned.

The default value for the Sedimentation Duration is 90 or 60 seconds, depending on the Cell Type. This can be shortened depending on the Cell Type. Please consult with the local Roche Technical Service before choosing other sedimentation times.

5 Ensure that the IR Operator is set to CXHiResImageOperator.

Do not select either the IR Operator DBDMOperator or the IR Operator IlluminationTestImageOp-erator, if they are available. These IR Operators are designed for service purposes only and are not intended for analysis of cells. The parameters for these Operators should not be changed!


The Cell Type dialog box will automatically close.

The Cell Type List dialog box will be active again and include the newly created Cell Type in the list.

2.2.2 Modify the Parameters for the New Cell Type via the Live Operator Dialog Box

1 Highlight the row of the new Cell Type in the Cell Type List dialog box.

2 Click on the LIVE OPERATOR button.

The Live Operator dialog box opens.

3 In the Data Source area, select the Work Area, System Name, Reactor ID, Sample ID, and Data Set of the measurement for which the image analysis is to be improved.

The parameters for the loaded measurement are preset.

4 Select an image from the measurement in the Image No. field.

This image will be loaded and displayed in the dialog box with the living cells marked with green circles and the dead cells marked with red circles.

ccc




CC

5 Make the desired modifications, using the sliders, to a single parameter first.

In the example shown in the figure above, some live and dead cells were not recognized. This is most likely due to the fact that some of the cells fell below the cutoff for minimum size and also had an unusually weak contrast against the background.

For this particular cell culture, the following changes were made to the Cell Type New Cell Type (for more detailed information about available parameters, see the Cedex HiRes Analyzer Operator’s Guide):

c CMinSize set to: 4

c LCAppearance set to: 10

c DCAppearance set to: 10

Image analysis with Std. Size before parameter adjustments.

Image analysis with New Cell Type after parameter adjustments.

The labeling of the cells can be switched on and off using the checkboxes in the upper-right hand corner in order to allow for better evaluation of the results from changes in parameter settings.

6 As soon as each parameter is changed, the data is automatically reprocessed. If multiple parameter changes are made at the same time, remove the checkmark in the Automatic process box by clicking on it. When the checkmark is removed, the button Process now becomes active. Make all changes, and then click on the Process now button for an analysis based on the new parameter settings. The image display shows the reprocessed image, as well as changes in the number of live and dead cells identified by the new Cell Type:

c The values New Viable Cells (the number of living cells in the current image) and New Dead cells (the number of dead cells in the current image) are displayed in the New column of the Process Data area.

c If an Operator parameter is modified, the newest values will appear in the New column after the automatic reprocessing of the selected image is finished.

c The values of the previous processing are displayed in the Previous column.

c In addition, Viability [%] in the New column shows the viability of the last processing of the image, while Viability [%] in the Previous column shows the viability of the second-to-last processing of the image.

Thus it is possible to directly compare the evaluation with each previous evaluation. By activating the Fixed checkbox in the Process Data area, the values currently displayed in the Previous column will not be changed after further adjustments of operator parameters. This allows, for example, the comparison of evaluations with the original evaluation when activating the checkbox after the first parameter adjustment. By clicking the Show original process parameters button you can see the process parameters originally used.

ccc




CC

7 Continue to adjust parameters until you find an optimized adjustment of the Operator parameters.

Use of the sliders, especially in combination, can lead to unexpected results.

8 Click on the SAVE button to confirm the modifications for the new Cell Type.

Click on the CANCEL button to close the Live Operator dialog box without saving changes.

n

Eleven parameters are available for adjusting the Cell Type. For parameter details and the effects of changing them, see the Cedex HiRes Analyzer Operator’s Guide.

Existing Cell Types can be edited and deleted. For more information on these actions, see the Cedex HiRes Analyzer Operator’s Guide.

2.2.3 Reprocess the Measurement Using the New Cell Type as the Basis for the Image Analysis

Reprocessing of previous measurements cannot be performed while the Cedex HiRes Analyzer is measuring a cell sample.

To reprocess existing data sets using the new Cell Type (e.g., New Cell Type):

1 Click on the LIST button in the Cedex Control Center to open the Measurement List dialog box.

2 Select the row of the measurement to be reprocessed and click on the REPROCESS button in the bottom right-hand corner.

The Measurement dialog box opens, containing all the result data for that measurement.

3 Enter a new name for the data set in the Data Set field of the Sample Parameters area (e.g., reprocess 1, as shown in the figure below).

4 Select the new Cell Type to be used for the image analysis (e.g., New Cell Type) in the Processing Parameters area.

You can also change the dilution factor in the appropriate field of the Sample Parameters area.

5 Click on the REPROCESS button in the center of the Measurement dialog box to start reprocessing the mea-surement based on the newly selected parameters.

6 When the reprocessing is finished, a dialog box will open asking whether you want the new data set to be the effective data set.

Click on YES if this is the case (see Effective Data Sets on the following page).

n

The new data set is available in the Measurement List dialog box once the evaluation is complete. All changes can be retraced by viewing previously created data sets via the Measurement List dialog box.

The reprocessing procedure creates additional data sets. Original data is not overwritten.




CC

Effective Data Sets

When measurements are reprocessed, it is possible to label one of the resulting data sets as Effective. The Effective Data Set is the version of the measurement (original or reprocessed) that has the correct parameters. Once a data set has been selected as Effective, it will be labeled as such in the Measurement List dialog box.

To later change the data set to be labeled Effective:

1 Select the data set version of the measurement to be labeled Effective in the Measurement List dialog box.

2 Click on the REPROCESS button.

A Measurement dialog box will open containing the results for that data set.

3 Check the Effective option in the Measurement dialog box.

4 Close the Measurement and Measurement List dialog boxes.

When the Measurement List dialog box is reopened, the newly selected data set will appear as the Effective Data Set.

Working with the Multi Sampler — (April 2014)



The position of the Cedex Sample Cup used for the Prime, LM Shutdown, calibration and cleaning routines is called the DefaultCup. An empty Cedex Sample Cup must be manually placed in the position set for the DefaultCup before running LM Shutdown, focus adjustment, Prime and all cleaning routines. This Cedex Sample Cup does not differ from the usual sample cups. The standard (default) position for the DefaultCup is position 1 of the Multi Sample Tray.

Using the Multi Sample Tray

To insert the tray, gently push the tray into the notch until the automatic tray rope starts pulling it in. To eject the tray, gently push on the tray. The tray will be automatically ejected. The tray can only be ejected when the system is idle. It cannot be ejected if the system is moving or the needle is down in a cup.

Carrying out a Measurement with the Multi Sampler

1 Click on the MULTI RUN button on the Cedex Control Center to open the Multi Run dialog box.

2 Fill 300 µL +/- 10% of the samples to be measured into individual Cedex Sample Cups (maximum 20) and place them in the Multi Sample Tray according to the desired sequence. Insert the tray into the Multi Sampler.

3 Click anywhere in the row of the Multi Run preparation area that corresponds to the location of a cup containing a sample. The row will be converted to edit mode, and the sample and process parameters for the measurement can be defined.

4 Enter the sample data and parameter information as described in the section “Carry out a single measurement ” in the Quick Guide “Performing a Measurement ”.

5 Repeat steps 3 — 4 for the remaining samples to be measured.

6 Activate the status of each sample row by double clicking in the Status field of the row to be activated. The row appears pale blue, and further modifications of sample information is impossible. Return to the Edit status by double clicking on the Status area of the sample row to allow for further changes, if desired.

7 Alternatively, activate or deactivate all samples simultaneously by double clicking on the word Status in the column heading at the top of the Multi Run preparation area. Confirm the safety query with YES to accept the modification.

8 After some or all rows have been activated, click on the START button on the right-hand side of the Multi Run dialog box to start the analysis of the activated measurements.

Sample rows in which data has not yet been entered can be filled out at any time while the Multi Run is running. In addition, sample rows containing finished measurements (status: done) can be cleared and prepared for a new measurement by double-clicking in the Status field of the row with the finished measurement. Sample data for a measurement cannot be modified after that measurement has begun.

Viewing results via the Multi Run Result List

At the bottom of the Multi Run dialog box, the Analyzed Measurements field displays the list of results for measurements previously carried out. Measurements are listed in order of process time, from the newest measurements at the top of the list to the oldest measurements at the bottom. All measurements carried out using the Multi Run dialog box will be displayed in this field unless the Clear Resultlist button has been pressed, which will clear all measurement results from the list.

In addition, measurements displayed in this field can be restricted to only the measurements carried out by the user logged into the system (mine), measurements that have not yet been printed out (unprinted), and/or measurements carried out on that particular day (today).

Other results, such as Average Diameter, can be added for display in the result list via the User Preferences (see “Adjusting Result Display in the Measurement List and Multi Run dialog boxes” in the Cedex HiRes Operator’s Guide). Double-click on a measurement to view all results. If the result list has been cleared, previously carried out measurements can still be viewed, printed out and exported via the Measurement List dialog box (see “Using the Measurement List” in the Cedex HiRes Operator’s Guide).

15Prologue

Installed anti-virus software should never be set up to scan the the complete Cedex2 directory and especially not the database file (FDB file) itself.

If the system has been upgraded from some previous version to Software version 2.3.2, it is possible that some default settings in the System Options may have slightly different values than those described in this manual. The settings described in this manual apply to systems on which Software version 2.3.2 has been installed as the original Software.

The Software and hardware of your Cedex HiRes System can differ from the information described here, but this should not make a difference to the operational functions in general.

The manufacturer is not responsible or liable for any damages resulting from improper use or failure to comply with the regulations in the Operating Instructions.

FCC Notification

Changes or modifications to this unit not expressly approved by the party responsible for compliance may void the user’s authority to operate the equipment.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate frequency energy and, if not installed and used in accordance with the Instruction Manual, may cause harmful interference to radio communications. Operating this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at their own expense.

Electrical Safety

The Cedex HiRes Analyzer is designed in accordance with Protection Class I (IEC). The chassis/housing of the instrument is grounded to protection earth (PE) by means of a cord. For protection against electrical shock hazards, the instrument must be directly connected to an approved power source such as a three-wire grounded receptacle for the 110 V or 230 V line. Do not use an ungrounded receptacle; have a qualified electrician replace the ungrounded receptacle with a properly (PE) grounded receptacle in accordance with the local electrical code. Do not use an extension. Any break in the electrical ground path, whether inside or outside the instrument, could be hazardous.

Under no circumstances should the user attempt to modify or deliberately defeat the safety features of this instrument. If the power cord becomes cracked, frayed, broken, or otherwise damaged, replace it immediately with the equivalent part from Roche Diagnostics.

Malfunction due to interfering electromagnetic fields

Malfunction of system and incorrect results due to interfering electromagnetic fields

This system is designed and tested to CISPR 11 Class A standard. In a domestic environment it may cause radio interference, in which case, you may need to take measures to mitigate the interference.

c The electromagnetic environment should be evaluated prior to operation of the device.

c Do not operate this system in close proximity to sources of strong electromagnetic fields (for example unshielded intentional RF sources), as they may interfere with proper operations.



XII. Disposal of the Analyzer

Disposal Recommendations

All electrical and electronic products should be disposed of separately from the municipal waste system. Proper disposal of your old appliance prevents potential negative consequences for the environment and human health.

The analyzer must be treated as biologically contaminated hazardous waste. Decontamination (i.e., a combination of processes, including cleaning, disinfection and/or sterilization) is required before reuse, recycling, or disposal.

Dispose of the analyzer according to local and/or laboratory regulations.

For more information, contact your local Roche Support personnel.

Disposal of control unit components

This symbol appears on any component of your control unit (such as the computer, monitor, or keyboard) that is covered by the European Directive on Waste Electrical and Electronic Equipment (WEEE).

You must dispose of these items through designated collection facilities appointed by government or local authorities.

Contact your city office, waste disposal service, or your Roche Service representative for more infor-mation about disposal of your old product.

Constraint:

It is left to the responsible laboratory organization to determine whether control unit components are contaminated or not. If contaminated, treat them in the same way as the system.

Disposal of the Analyzer

17Overview

AAA Overview

The Cedex HiRes Analyzer automatically determines the cell concentration and viability of cell suspensions. The analysis is based on the Trypan Blue Exclusion Method whereby cell suspensions are stained and analyzed. The data obtained allows for the evaluation of the overall state of the cell culture, including the specific growth rate and doubling time of a cell population, as well as the documentation of the cultivation process.

The evaluation of the samples is based on automatically obtained digital images that are analyzed using analysis Software on a separate computer (Cedex HiRes Control Unit). All the necessary steps – from the staining of the samples to the recording and evaluation of the image data – are automatically performed by the Analyzer. Recognition and differentiation of cells as either viable or dead is done under standardized conditions, which provides very precise and objective results.

A variety of parameters, including Viable Concentration, Total Concentration, Viability, Total Object Count, Average Compactness and Average Diameter are analyzed using result data from single images, as well as from all of the selected images of a sample. Standard deviation (Std. Dev.) of the number of cells from image to image is also calculated. In addition, the Aggregate Rate, which shows the percentage of the total number of cells that appear in aggregates (clusters), is determined for both single images and all of the images. The use of a Live Operator makes it possible to directly observe the effects on the analysis of a sample when the image analysis Software (Operator) is adjusted.

Graphical representations of the measurement results can be viewed in the Measurement Statistics Histogram, Diameter Histogram, Compactness Histogram, Aggregate Histogram and Cultivation Time Chart. In the Measurement Statistics histogram, individual images can be compared to give a better overview of the distribution of the cells in the images. The Cell Diameter Histogram shows the diameter distribution of living cells. The Object Diameter Histogram shows the diameter distribution of all objects detected such as cells, debris, air bubbles and viable and dead cell aggregates. The deviation of the shape of living cells from that of an ideal sphere is represented in the Compactness Histogram. The Aggregate Histogram provides an overview of the amount and size of aggregation found in the cell culture.

The Cultivation Time Chart displays growth curves and cultivation parameters in a time- dependent manner. The results of the Cultivation Time Chart can be separately printed out. For further processing of the results in other programs, data export in formats such as Excel-compatible formats and CSV (Comma Separated Values, generally applicable) is possible. The Cultivation Time Chart includes calculations for the doubling time [T] and specific growth-rate [μ].

The Cedex HiRes Software 2.3.2 is operated on Windows® 7. Secure data handling, as well as a carefully designed user management system, guarantee compatibility with 21 CFR Part 11. Access security for the Cedex HiRes System has been stepped up. Access is only allowed for authorized persons. The workstation can be automati-cally blocked after a certain number of consecutive entries of a false password via the Systems Options. A warn-ing message will appear before the last allowed attempt.

Contact your local Roche service representative for more information about setting up the Cedex HiRes System to be compliant with 21 CFR Part 11.

The flow chamber is specially developed to allow for the analysis of a defined volume of cell suspension. The Liquid Management system is responsible for staining the sample as well as for filling and cleaning the flow chamber and liquid feed system.

The volumes of sample and dye, as well as specific cleaning solutions required for each cleaning routine, are precisely controlled via the syringe module with the 8-way distribution valve. The individual components of the Liquid Management system are easily accessible to allow for trouble-free maintenance and control.

Description of the Cedex HiRes System

19Overview

AA2 The Measurement ProcedureThe determination of the number of viable cells (cells/ml) and viability of cell suspensions (the percentage of viable cells from the total cell sample) is a fully automated, standardized procedure based on the manual Trypan Blue Exclusion Method. A defined volume of Trypan Blue is added by the syringe to the Cedex Sample Cup containing the cell suspension. The cell suspension and dye are optimally mixed between the syringe and Cedex Sample Cup by controlled pump actions and then incubated for exactly the same amount of time for each measurement. This minimizes effects on the viability measurements that might be caused by the toxicity of the Trypan Blue.

After the incubation period, the stained cell suspension in the syringe is then transported in one portion via the capillary tubes and the 8-way valve into the precision flow chamber, which is scanned by the scanner. The scanned image of the flow chamber is then divided into smaller images for evaluation.

Once the measurement procedure is completed, the Liquid Management system automatically performs a cleaning routine. It is only possible to start a new measurement after the cleaning routine has finished.

The Trypan Blue Exclusion Method

The Trypan Blue Exclusion Method is based on the principle that viable cells will not take up the dye, while dead or dying cells have a compromised membrane that allows for the up take of the dye. Thus, dead cells appear darkly stained.

Trypan Blue has a greater affinity for serum proteins than cellular proteins. If the image has a dark background due to high quantities of stained serum proteins, centrifuge the cell sample and resuspend it in a protein-free medium or physiological saline solution prior to counting.

The Measurement Procedure


AA 3 Data Analysis The analysis Software and its graphical user interface (GUI), known as the Cedex Control Center, enables the user to work with the Cedex HiRes Analyzer. The image analysis Software (Operator) recognizes structures and identifies particles, thus differentiating cells from cell debris and dirt particles. Live and dead cells are differentiated according to their degree of Trypan Blue staining.

The image processing is integrated in the Cedex Control Center in such a way that the user or Administrator can check on its function in the system. The analysis process cannot be altered during data recording in order to allow for consistent and objective measurement results.

B System Description

1 Installing the Cedex HiRes SystemThe Cedex HiRes System comprises the Cell Analyzer and the Control Unit (PC equipped with the Cedex HiRes Software 2.3). The Cell Analyzer and Control Unit are delivered and assembled by a service technician authorized by Roche Diagnostics GmbH. The service technician assembles the Cell Analyzer and controls the installation, runs the focus adjustments and ensures that the Cedex HiRes System is operational. Finally, the technician will create a report on the installation and current status of the device.

We recommend choosing your local IT specialist as the system administrator for the general administration of the Windows operations. This person controls the configurations that regulate system access at the level of the operating system.

Installation of the Cedex HiRes System is done as follows:

c The system administrator should set up net access and/or printer installation, if desired, before the service technician assembles the Cedex HiRes System.

c The Cedex HiRes System is assembled by a service technician authorized by Roche Diagnostics GmbH.

c The service technician installs the Analyzer and checks the settings in the Software.

c The service technician checks the Software information, performs a focus adjustment and ensures that the Cedex HiRes System is ready to use. Finally, the technician creates a current status report of the device.

c The system administrator is responsible for setting up the user accounts for the operating system. The system administrator is also responsible for ensuring data safety and security of the system.

c The Administrator for the Cedex HiRes Software then sets up Cedex HiRes System user accounts and assigns users the appropriate rights (see “Administration of User Accounts”).

Please be aware that the correct operation of the Analyzer and Software can only be guaranteed if no other Software has been installed on the computer.

Roche recommends only installing the software on the Control Unit and Windows Image version provided by Roche, specifically for the Cedex HiRes System. Installations on other hardware will not be supported. For more details, please contact Roche Technical Service.

The Software and hardware of your Cedex HiRes Analyzer may differ from the information described here, but this should not make a difference to the operational functions in general.

6 Securing Access Rights

6.1 Access Control at the Windows Operating System LevelWe recommend choosing your local IT specialist as the system administrator for the general administration of the Windows operations. This person should undertake the configuration of the settings that regulate access to the system at the operating system level. One default user at the operating system level is factory installed:

c The Win-Admin user (default password Win-Admin) acts as system administrator for the operating system and has full access to all elements on the desktop including the ability to add/delete programs.

For security reasons, the Win-Admin user at the Windows Operating System level should protect the access to the Windows OS with a new password directly after initial installation.

6.2 Access Control at the Cedex HiRes System Software LevelTo launch the Software, do the following:

1 Check that the Cedex Server Software has already been automatically started (it may appear as a minimized dialog box in the task bar at the bottom of the computer screen). If it is not automatically started, start the server by double-clicking on the Cedex Server icon on the desktop.

2 Start the Cedex HiRes Software by double-clicking the Cedex Client icon on the desk top (the Cedex Server must be successfully launched before the Cedex Client can be started). The Log In dialog box of the Cedex HiRes System will open.

3 Enter the username and password in the respective fields. By default, the following users are available after installation:

a. Superuser (password spass)

b. Administrator (password apass)

■

For the Cedex HiRes Software, there should generally be at least three levels of users. In addition to normal Cedex HiRes System users, who will only use the Cedex HiRes System for carrying out measurements, both a Cedex HiRes System Superuser and an Administrator should be appointed. The Cedex HiRes System Super-user assumes the main responsibility of handling the Cedex HiRes System, whereas the Administrator creates and administers user accounts.

For security reasons, both the Administrator and Superuser should protect their access to the Cedex HiRes Software with new passwords after initial installation. Follow the instructions below to secure access and define a new password:

1 Log in as Administrator or Superuser.

2 Click on the System menu in the Cedex Control Center.

3 Click on Change own password. The Change Password dialog box appears.

4 Enter the old password first. The new password needs to be entered twice.

5 Confirm by pressing OK.

■

After logging in, users can change their own passwords at any time by following the same procedure.

After installation, the user Administrator should set up user accounts and provide the necessary rights before regular users run measurements (see “Administration of User Accounts”).

For security reasons, the Cedex HiRes Software Administrator is generally only given administrative rights and cannot carry out, reprocess or view measurements.

Access rights to routine operations vary depending on the configurations set by the Administrator. Access rights may vary according to options chosen for each user account. See “Administration of User Accounts” for more information about access rights.

2 The Measurement Dialog Box

2.1 Preparing Samples for Measurement

1 Transfer 300 µl of a well-mixed cell suspension to a clean Cedex Sample Cup.

The Cedex HiRes Analyzer tolerates volume variations of +/- 10%. Any greater variation in sample volume will lead to inaccurate results. The Cedex HiRes Analyzer can determine cell concentrations in the range of between 5× 104 – 1× 107 cells/ml. Any higher concentration requires a manual dilution. Cells with a diameter range of between 2 μm – 40 μm can be assessed accurately. Object recognition performance lies between 1 μm and 90 μm.

2 Place the prepared Cedex Sample Cup containing the cell suspension in the appropriate cup position on the Multi Sample Tray or attach to the sample port.

■

2.2 Setting up a Single Measurement in the Measurement Dialog BoxOnce samples are prepared, set up a measurement in the Measurement dialog box of the Cedex Control Center as follows:

c In the Cedex Control Center Shortcuts area, click on the MEASURE button to open the Measurement dialog box.

c Define the Sample Parameters in the Sample Parameters group.

c Define the Measurement and Analysis Parameters in the Processing Parameters group.

c Click on the START MEASUREMENT button to start the measurement process.

Figure 80

The Measurement Dialog Box

Preparing Samples for Measurement


CC

Step-by-step descriptions for performing measurements via the Measurement dialog box are provided in Section B, Chapter 1, “Setting Up a Single Measurement in the Measurement Dialog Box”, in the Cedex HiRes Analyzer User Training Guide.

For undiluted samples, enter a dilution factor of 1:1. A dilution of 1:2 refers to a mixture of one part cell suspension and one part dilution medium. A dilution of 1:5 means that one part cell suspension has been added to four parts dilution medium, etc. You may need to manually dilute samples with very high cell densities (>1 × 107 cells/ml) prior to measuring.

The dilution ratio chosen from the list only relates to the manual dilution of the sample prior to placing the sample on the system. Dilutions that are an automatic part of the measurement process in the Analyzer are already taken into account by the Cedex HiRes Software; those calculations are automatically performed and are not related to entered dilutions.

One image in the Cedex HiRes Software 2.3 corresponds to approximately 25 images in the Cedex HiRes Software version 1.10. Thus a ‘Minimum’ precision (3 images) roughly corresponds to 75 images of Software version 1.10 of the Cedex HiRes Software, while ‘Normal’ precision roughly corresponds to 150 images, ‘Superior’ precision to 200 images, and ‘Maximum’ precision to 275 images.

2.3 Interrupting a MeasurementAn orange EMERGENCY STOP button is located on the left-hand side of the Measurement dialog box and can be activated during the measuring procedure to interrupt the analysis process. If the EMERGENCY STOP button is selected, an error message appears asking, “Do you want to cancel the process?” Select YES to stop and abort the process immediately. Select NO to put the process on hold.

If YES is selected, the EMERGENCY STOP button changes to read UNLOCK QUEUE. Before more measure-ments can be run, the system must be unlocked by clicking on this button. If NO is selected, the EMERGENCY STOP button changes to RESUME. Click on RESUME to resume the measurement process.

Only use the ‘EMERGENCY STOP’ button in an emergency. Actual measurement data may be lost.

2.4 End of MeasurementA cleaning procedure automatically begins immediately after the scanning ends. The entire Liquid Management system is rinsed during this procedure (Ultra Fast Clean). Once this procedure is complete, a green bar appears in the Measurement dialog box, and the message “Process finished EndEvent (Measurement)” appears in the Event window on the Cedex Control Center.

Figure 81

To set up a new measurement, click on the NEW MEASUREMENT button. If the next measurement belongs to the same Reactor ID as previous measurements, the consecutive Sample ID will be automatically entered into the Sample ID area by the analysis Software without further entries being necessary. If a different Sample ID is desired, the new Sample ID can be typed in manually.

In the case of single measurements run via the Measurement dialog box on a Cedex HiRes System with a Multi Sampler attached, the Software will automatically and incrementally increase the sample cup position number with each new measurement. The cup position can also be fixed (see “Turning off Automatic Incrementation of Sample Cup Position”).

When the final measurement in a set of samples is complete, or if there is a longer pause before the next measurement, perform a Standard Clean of the Liquid Management system (see “Cleaning Options”).

Ensure that Cedex Sample Cup from the last measurement remains in the Multi Sample Tray in the DefaultCup position during the complete cleaning procedure, or attached to the sample port. Only remove the cup when a new Cedex Sample Cup is placed in the Multi Sample Tray.

Before shutting down the Cedex HiRes Analyzer, and at the end of the day, perform an LM Shutdown procedure (see “The Hardware Management Dialog Box”).

3.3 Disruption of MeasurementsError messages may appear if a sample cannot be run. For example:

c The No Cup message appears when a Cedex Sample Cup is not available in its position on the Multi Sample Tray during measurement.

c The Tray not inserted message appears when the Multi Sample Tray is not inserted or not inserted correctly.

Some errors may block the analysis of the rest of the measurements. The level of error that should stop the analysis of all samples is determined using the Error Level drop-down list at the top of the Multi Run dialog box. The options for the level of error that will stop the analysis are:

c Fatal: Only errors involving a system / hardware crash, when functionality is not available, will stop analysis.

c Critical: Data loss or any other error that results in an invalid measurement will stop the analysis.

c Error: Errors that do not result in an invalid measurement will stop the analysis.

c Warning: Warning messages with information for the user will stop the analysis.

c Message: Any message will stop the analysis.

Information Note: If a problem occurs with the system when the needle is down, restart the Hardware Management to render the tray ejectable again (see “The Hardware Management Dialog Box”). In some cases it may be necessary to restart the Cedex HiRes Analyzer and Software.

3.4 Nonlinear Measurements in a Sample SeriesMeasurements of activated samples are always done in a linear fashion following a sequence of 1–20. If samples need to be analyzed individually and not in the usual linear ascending order of 1–20, the samples to be analyzed later should be inactivated and remain in the edit status. When all active samples in the Multi Sample Tray are completed, subsequent measurements with the newly activated samples can begin.

In addition, the Result Data area for the individual images has an Excluded column next to the image number. Images that could lead to incorrect measurement results during analysis (e.g., due to impurities or large bubbles), are automatically recognized as invalid and excluded from evaluation by the analysis Software. If this occurs, the image will be marked with a check in the checkbox of the Excluded column. Users can also manually exclude individual images from the calculations or include images that were automatically excluded by the Software by clicking on the checkbox in this column.

4.2 Sample Parameters and Processing Parameters AreasThe Sample Parameters area of the Measurement dialog box shows the parameters entered by the user before running the measurement. If any measurements have been reprocessed, the original or reprocessed data can be selected in the drop-down menu of the Data Set section. If data has been reprocessed at some point, the Effective checkbox will indicate which data set was determined to be the effective version (see “The REPROCESS Button”). Comments for the measurement can be added in this area at any time.

The Processing Parameters area lists the process parameters of the measurement, including Cell Type, used to analyze the images (see “Adjustment of the Image Analysis using the Live Operator”), the precision selected and the date and time the process was run. None of the values in this area can be changed. Click on the SHOW PARAMETERS button below the Cell Type drop-down menu to open a dialog box that shows the Live Operator Parameters values used for that Cell Type:

4.3.2. Viewing an Image Using the Image View Dialog Box

It is possible to see which cells were marked viable and dead cells by the analysis Software via the Image View dialog box. The user can thus get a sense of how cell shapes and clusters have been evaluated by the Software. The Cedex HiRes Software offers various options for optimizing measurement results by adjusting the Operator used for the image analysis. Thus, the image analysis Operator can be adjusted for unusual cell culture images or for specific internal counting strategies. For more information about adjusting the image analysis, see “Adjustment of the Image Analysis using the Live Operator”.

The Image View offers the following information and options:

c Viable Cells: number of viable cells.

c Dead Cells: number of dead cells.

c Show Circles checkbox: switches on/off the marking of cells recognized as living or dead. Viable cells are marked with a green circle and dead cells are marked with a red circle. The circle diameter corresponds to the cell diameter. Objects are marked with a blue circle.

c Zoom: Image enlargement.

c Brightness and contrast settings.

4.3.3. Excluding Images from the Evaluation Process/Including Excluded Images

Images can be excluded from analysis by the user. Also, images that have been excluded automatically by the analysis Software (due to, for example, excessive bubbles or dirt) can be included in the result analysis, if desired. Exclusion and inclusion of images for a particular measurement are done via the checkbox in the Excluded column in the Result Data area of the Measurement dialog box.

If there is a check in the Valid checkbox, the image is considered valid, which means that the cell image has been included in the calculation process. The user can choose to manually exclude the image by clicking on the checkbox in the Excluded column for the selected image. The image will still be marked as Valid, but will also be excluded from the calculation of results.

No check in the Valid checkbox means that the cell image is not considered valid and has been automatically excluded from the calculation process. In that case, a checkmark will automatically appear in the Excluded column. To include an image that was excluded by the Software, click away the checkmark in the Excluded column. The image will still be marked as invalid via the lack of checkmark in the Valid checkbox, but will be included in the calculation of results.

Should striped shadows or lines appear on the images, a new focus adjustment needs to be run as poor image quality can affect the results of the measurement (see “Automatic Adjustment and Alignment Verification”).

4.3.4. Viewing the Prescan Image

During a measurement, a so-called Prescan is carried out before the cells are scanned. The entire flow chamber is scanned in order to identify impurities and bubbles that may influence the measurement. The Prescan image is stored together with the measurement and can be viewed when the Measurement dialog box with results has been opened for that measurement. If the quality of the chamber condition is not good enough, there will be no check in the Valid checkbox under the Image area, and a note will be placed in the Audit Trail File that dirt was detected.

The Prescan image for a particular measurement can be accessed via the VIEW PRESCAN button located in the Image area of the Measurement dialog box. To open an Image View dialog box containing the Prescan image, do the following:

1 Click on the VIEW PRESCAN button in the Image area of the Measurement dialog box. A part of the Prescan image will appear in the Image dialog box.

2 Double-click on the Prescan image; the Image View dialog box containing the full Prescan image will open.

A number of actions can be carried out in the Measurements List dialog box including searching for measurements using a variety of filters, viewing measurement sample and process parameters, viewing measurement results, printing reports, exporting measurements to a file and reprocessing measurements.

5.1 Viewing Analysis ResultsView existing data sets by double-clicking on the measurement or by highlighting the row containing the desired measurement and then clicking on the VIEW button in the bottom right-hand corner of the Measurement List dialog box. This will open a Measurement dialog box containing all of the relevant data results for the selected measurement (see “Results Displayed in the Measurement Dialog Box”).

5.2 Searching for MeasurementsIt is possible to search for measurements using a number of different filter criteria including sample drawing date, process date, Reactor ID, and Sample ID in the Filter By area at the top of the Measurement List dialog box. To search for measurements based on the sample drawing date or the process date, for example, do the following:

1 Click on the drop-down menu button next to the Sample Drawing Date From or Process Date From sections. A calendar will appear in which the desired starting date for filtering can be selected.

2 When a date has been selected, a check will appear in the checkbox next to the date to indicate that a filter is active based on that date.

3 Click on the drop-down menu button next to the date in order to select the desired ending date.

4 Once the dates for filtering the measurements have been selected, click on the FIND button in the upper right-hand corner of the Measurement List dialog box.

5 All of the measurements that match the dates given for sample drawing (using the Sample Drawing Date From section), or that were run within the dates specified in the Process Date From section, will be displayed in the measurement list in the bottom half of the dialog box.

■

It is possible to select measurements with regard to both sample drawing date and process date. If the desired dates for both the sample drawing dates and process dates are selected, only those measurements that meet all 4 date criteria will be displayed when the FIND button is clicked on.

Measurements can also be searched for based on Reactor ID and/or Sample ID by filling in the information in these sections of the Filter By area. In addition, measurements can be searched for based on user by typing in the user name in the User section, by work area (using the drop-down menu in the Workarea section), by data set (in the DataSet area) and by Cell Type (using the drop-down menu in the Cell Type section).

If a measurement has been reprocessed, the original and all reprocessed versions of the measurement will be listed. The data set version of a particular measurement that has been selected as the Effective data set will have a check in the checkbox of the DSEffective column. The original data set of a particular measurement will have a check in the checkbox of the DSOriginal column (see “Effective Data Sets”).

6 Editing Existing Analysis Results/Data SetsThe Cedex HiRes Software allows for existing measurement results or data sets to be modified and reprocessed. These changes are done on existing Software data (image and analysis results) and, therefore, do not require any adjustments to the Analyzer. Existing measurement results can be edited via the REPROCESS button in the lower right-hand corner of the Measurement List dialog box.

6.1 The REPROCESS ButtonReprocessing existing measurement results/data sets (i.e., viewing a set of image data and evaluating them with new analysis parameters), can be done in the Reprocess mode, which is only accessible to authorized system users.

The reprocess mode offers the following options:

c Enter, modify or delete a comment.

c Correct the dilution.

c Change the Cell Type.

To reprocess a measurement, do the following:

1 Open the Measurement List dialog box by clicking on the LIST button in the Shortcuts area of the Cedex Control Center or by selecting the Measurement List option in the Measurements menu of the Control Center.

2 Highlight the row of the measurement to be reprocessed and click on the REPROCESS button in the lower right-hand corner. A Measurement dialog box will open containing all of the result data for that measurement.

3 Enter a new name for the data set in the DataSet section of the Sample Parameters area.

4 Make the desired changes to the new data set. Changes can be made with regard to the comment, dilution factor and Cell Type in the appropriate sections of the Sample Parameters and Processing Parameters areas.


5 Click on the REPROCESS button in the center of the Measurement dialog box to start the reprocessing of the measurement based on the new parameters.

6 When the reprocessing is finished, a dialog box will open asking whether the new data set should be the effective data set (see “Effective Data Sets”).

■

A new data set is available once the evaluation has been completed. All changes can be retraced by viewing previously created data sets, which are shown in the Measurement List dialog box.

The reprocessing procedure creates additional data sets. Original data is not overwritten.

Reprocessing of previous measurements cannot be performed while the Cedex HiRes Analyzer is measuring a cell sample.

6.2 Effective Data SetsWhen measurements are reprocessed, it is possible to label one of the resultant data sets as Effective. The Effective data set is the version of the measurement (original or reprocessed) that has the correct parameters. Once a data set has been selected as Effective it will be labeled as such in the Measurement List dialog box.

It is possible to later change which data set is labeled the Effective data set by doing the following:

1 Select the data set version of the measurement to be labeled Effective in the Measurement List dialog box.

2 Click on the REPROCESS button. A Measurement dialog box will open containing the results for that data set.

3 Click on the box to the left of the word Effective in the Measurement dialog box. A check will appear in the box.

4 Close the Measurement dialog box.

7 Graphical Display of the Analysis ResultsIn addition to displaying the overall analysis values, the Cedex HiRes Software can also display graphic diagrams of the results. These diagrams can be viewed after the analysis is finished by clicking on the DIAGRAMS button in the Result Data area of the Measurement dialog box. When the DIAGRAMS button has been selected, the Diagram dialog box will open. 5 different histograms are available: Aggregate Histogram, Cell Diameter Histogram, Compact Histogram, Object Diameter Histogram and Measurement Statistics. Click on the respective button to open the desired histogram.

All the results represented in the diagrams are based on valid images accepted for evaluation. This means that individual images may be sorted out due poor quality (e.g., bubbles, dirt particles, etc) in the interest of an accurate measurement result. This is done automatically by the analysis Software or manually by the user (see “Excluding Images from the Evaluation Process/Including Excluded Images”).

7.1 Enlarging the HistogramsCertain areas of the histograms can be enlarged by following the instructions below:



3 Release the mouse button and the selected area will fill the complete dialog box.

7.2 Aggregate HistogramThe Cedex HiRes Analyzer offers an evaluation of aggregates in cell cultures. Click on the AGGREGATE HISTOGRAM button in the Histograms dialog box to open the corresponding histogram dialog box.

The Aggregate Histogram shows the number of cells in the cell culture found in aggregates, as well as how many cells each aggregate is composed of. Both the actual cell number and the percentage distribution can be displayed.

Figure 91: The Aggregate Histogram, detailed view (divided into living and dead cells), here: (absolute) number of cells

The Number of Cells [#] identified is displayed on the y-axis and at the top of the bars. The Aggregate Size, in terms of the number of cells per aggregate, is given on the x-axis. Figure 91 shows, for example, that 148 living and 40 dead cells of all identified cells were found in aggregates of two cells.


Aggregate Histogram


CC

The percentages can be displayed using the PERCENT button.

Figure 92: The Aggregate Histogram, detailed view, here: percentage distribution of cells

The percentage of cells [%] found in aggregates compared to the total live or dead cell count is displayed on the y-axis. The aggregate size, in terms of the number of cells per aggregate, is given on the x-axis. Figure 92 shows, for example, that 3.66% of all living cells and 7.29% of all dead cells are found in aggregates of two cells.

The Total Cell Count (living and dead cells combined) per aggregate is mapped in the histogram using the TOTAL button. Figure 93 shows, for example, that 188 cells of the measurement are found in aggregates of two cells.

7.4 Object Diameter HistogramClicking on the OBJECT DIAMETER HISTOGRAM button brings up the Object Diameter Histogram (see Figure 96). Analogous to the representation of the diameter of the living cells, the diameter of all recognized objects is shown here, including objects such as cells, debris, air bubbles and viable and dead cell aggregates.

Figure 96: Object Diameter Histogram

7.5 Defining Diameter Intervals in the Diameter HistogramsThe Cell and Object Diameter Histograms have three sliders that can define separate diameter intervals. This allows division of a diameter histogram into a maximum of four parts. The sliders are activated by clicking on the corresponding boxes and moving the sliders to the desired positions. One can also define the margins of the intervals by entering the numerical values on the left-hand side of each slider.

The borders of the first interval are defined by the minimum value and the first numerical value entered. The next two values define the upper borders of the second and third intervals. The fourth interval is defined by the upper border of the third interval and the maximum value.

The number of viable cells, their percentage of the total viable cell number and the viable cell concentrations [× 105 cells/ml] are listed in a table for each of the individual intervals. Similarly, the number of the objects analyzed, their percentage compared to the number of all objects recognized, as well as the object concentration [× 105 objects/ml], are listed in a table under the Object Diameter Histogram for each of the individual intervals. The intervals set in the Cell Diameter or Object Diameter histograms can be saved for future reference.

7.6 Compactness HistogramThe ratio between the cell circumference and the cell area is based on an ideal sphere (4p), which is equivalent to the value >1< on the abscissa of the Cell Compactness Histogram. The extent of variation between the cell shapes and an ideal sphere is reflected in values being greater than 1. The shape of a cell is known as the Compactness. Click on the COMPACTNESS HISTOGRAM button to display a diagram that compares viable cell shapes to that of an ideal sphere.

If a significant number of cells (ordinate) have a high value, this could indicate improper handling of a sample. The Compactness Histogram can be used to check the state of the cell culture, for example, if the stirring speed is too high or nutrient composition is incorrect.

Figure 97: Compactness Histogram

This diagram is based on the compactness of all viable cells in the measurement.

CC

7.7 Measurement Statistics HistogramClick on the MEASUREMENT STATISTICS button to display a column diagram showing the total number of viable cells (green columns) and dead cells (red columns) found in the images analyzed.

Figure 98: Measurement Statistics histogram

In the bar diagram, the number of living cells is represented in green bars and the number of dead cells in red bars on top of the green bars. The COMBINE button, which appears when the Measurement Statistics histogram is open, can be used to combine several images to give a better overview of the whole sample. Conspicuous bars can thus be immediately identified, and the user can then view and assess the relevant images (see “Image Area”). The results of each individual image can be seen again by clicking on the SINGLE button. If an image has been automatically excluded by the Software or manually excluded by the user, the corresponding position in the diagram will be empty.

8.2 The Cultivation Time Chart Dialog BoxOnce a View has been created with the desired series of measurements to be used for a chart, the Cultivation Time Chart can be created using the VIEW CHART button.

The Cultivation Time Chart dialog box opens, offering several options for displaying and analyzing the created CTC.

8.2.1. The Data Selection Area

Which curves should be displayed in the diagram is determined in the Data Selection area of the Cultivation Time Chart dialog box. The following values can be selected for display:

c Viable Cell Conc.: Viable cell concentration [× 105 cells/ml]

c Total Cell Conc.: Total cell concentration [× 105 cells/ml]

c Viability [%]: Percent viability

c Total Cell Count: Total number of all cells counted

c Avg. Compactness: Average compactness of living cells [without unit]

c Avg. Diameter: Average diameter of living cells [μm]

c Std. Dev.: The deviation from image to image of the number of cells found in each image

c Aggregate Rate [%]: Percent of cells found in aggregates

c Dead Cell Conc.: Dead cell concentration [× 105 cells/ml]

c Viable Cell Count: The total number of viable cells counted

c Dead Cell Count: The total number of dead cells counted

The measurement series, including information about which measurements have been used to create the chart, are listed in the Data Series area in the bottom left-hand corner of the Cultivation Time Chart dialog box. A legend indicating the symbol (form and color) used for each parameter is at the top of the graph. The color used for each series is indicated in the Chart area in the lower right-hand corner of the dialog box.

The x-axis units can be displayed as either days [d] or hours [h]. Click on Time[d] below the x-axis to switch to hours. The x-axis calibration will be automatically recalculated.

Place the mouse pointer over a measurement point in the diagram to see detailed information about the measurement point including date, time and measurement results. Also, the graphic representation can be enlarged or scaled down again with the use of the mouse (see “Enlarging the Histograms”).

8.2.2. Fitting to the Lowest Common Value

The FIT LOWEST COMMON VALUE button enables automatic shifting of the zero-point of single measure-ment series to each other. The following can be selected:

c Viable Cell Density

c Dead Cell Density

c Total Cell Density

Using this function, the zero-point of each series can be automatically shifted on the x-axis in order to be able to better compare the measurement series to each other. The lowest common value of all the measurement series is automatically determined, and the graphs in the diagram are shifted to each other so that the lowest common value falls on the x-axis at the same point. While doing so, the left-most point of the graph of all the measurement points is set at value 0.

8.2.3. Measurement Series Offset

In the graph, measurement series are automatically displayed such that all measurement series begin at time 0. The different measurement series can, however, be best compared to each other when the beginning of the exponential growth phase (log phase) starts at the same time. Therefore, it is possible to shift the curves in the diagram by changing the offset for each series.

A button in the Offset column of the Data Series area displays the offset set by the user (the button displays 0 [h], if an offset was not set). Click on this button to open the Measurement Offset dialog box. The measurement series offset can be then manually shifted in this dialog box.

Figure 103: The Measurement Offset dialog box

The offset can be separately entered for each of the five measurement series by clicking the button with the corresponding number of the measurement series. Large time differences can be entered in days [d], small ones in hours [h] by clicking on the appropriate buttons [d]/[h] . The offset can be set by selecting the desired series number (colored boxes) and then moving the slider to the desired offset. Using the slider will cause an immediate shift of the measurement series in the diagram so that it can be immediately seen where the best position for a series is in the diagram.

The smallest time unit that can be set is 0.10 hours. The OK button confirms the offset values in the graphics.




CC

8.2.4. Variable Axis Calibration

The buttons lin and log are used to determine whether the y-axis should display in a linear (lin) or logarithmic (log) scaling for cell concentration data. The default value is linear.

The x-axis units can be displayed as either days [d] or hours [h]. Click on the Time[d] below the x-axis to switch to hours. The x-axis calibration and division will be automatically adjusted.

8.2.5. The Cultivation Time Chart – Exponential Regression Dialog box

Using the EXPONENTIAL REGRESSION button in the View section of the CTC Views dialog box, cell culture growth patterns can be displayed with their Specific Growth Rate [μ] and Doubling Time [T]. The corresponding values appear in the Data Series list (see Figure 104).

Figure 104: A view of the Exponential Regression dialog box

Only viable cell concentration will be shown in this graph. The measurement parameters Specific Growth Rate [μ] and Doubling Time [T] of the culture are computed by means of the differential curve. Additional information regarding the determination of the specific growth rate and the doubling time of cell cultures is provided in Section C, Chapter 1, “Monitoring Growth of Cells Over Time” of the Cedex HiRes Analyzer User Training Guide.

As with the Cultivation Time Chart dialog box, the Cultivation Time Chart - Exponential Regression dialog box also offers the possibility to shift the measurement series offset using the button in the Chart area and the options lin and log in the Regression area to define the y-axis scaling. Printing of the Cultivation Time Chart - Exponential Regression is enabled by the PRINT REPORT button.

10 Administrator FunctionsThe following system functions are generally only available to the Administrator and/or Superuser:

c Administration of user accounts

c Password management and assigning workareas

c Adjustment of the image analysis

c Securing data

10.1 Administration of User AccountsThe user usually has limited access rights. All administration rights relating to user accounts (i.e., creating, deleting, modifying and delegating rights), should remain exclusively with the Administrator.

All administration of user accounts and rights management is done in the User Rights Management dialog box. To open the User Rights Management dialog box, click on the Setup menu in the Cedex Control Center and select User and Rights Management.

The User Rights Management dialog box is structured with menus and sub-menus similar to the directories in Windows Explorer. The distinction between functions, roles, users and groups, which is mainly connected to the delegation of rights, is explained in the appropriate sections of this chapter. Password settings can also be configured in this area.

10.1.1. Creating User Accounts

Before creating new user accounts, the password configurations should be set up (see “Password Management”). Follow the instructions below to create a user account:

1 Click on the Setup menu in the Cedex Control Center.

2 Click on User and rights management. The User Rights Management dialog box appears.

3 Right-click on the All Users folder and click on Create new user. The User account area appears.

4 Enter the user’s first name and last name in the first and second rows and a username for the account in the third row.

5 Enter a temporary password for this user account in the fourth field. Click on Save to confirm. If the option, “must change on first login” is selected, the user will be forced to change the password the first time he or she logs into the Cedex Control Center.

6 Restart the Cedex Software application.

Administration of User Accounts

103Software

CC

10.1.2. Assigning Access Rights

The user is normally denied access rights to certain areas, such as administration of user accounts and sensitive system functions (focus adjustment, etc.). The user, therefore, will not necessarily be able to access all of the menus on the Cedex Control Center after login.

Access rights can be modified at any time by the Administrator. Rights are generalized in user roles that can comprise a single access right or a set of access rights. To grant rights, you will need to assign one or more user roles to a user. The following user roles are available after installation of the Software:

c Administrator

c Production Staff

c Research Staff

c Superuser

c Support

By default, the pre-installed Production Staff, Research Staff and Support roles have no functions assigned to them. More detailed information about assigning functions for each pre-set user role, as well as editing existing functions and creating new user roles, is located under “Creating and Editing User Roles”.

Follow the instructions below to assign rights to a user account:

1 Click on the Setup menu in the Cedex Control Center.

2 Click on User and Rights management. The User Rights Management dialog box appears.

3 In the All Users main menu, open the user account menu that is to be modified. A User Role sub-menu will appear.

4 Open the All Roles main menu and drag the appropriate user role from the All Roles menu into the All Users sub-menu. The access rights available for this user role will be added to the account. To deny certain access rights, the corresponding user role needs to be deleted from the All Users sub-menu. Right-click the user role which is to be deleted and click on Remove the role from the user.

■

CC

10.1.3. Creating User Groups

It is possible to generalize one or more user accounts in user groups. Instead of assigning rights to a single user, a user role or a set of user roles can be assigned to a user group. The whole user group, therefore, receives all access rights that have been assigned to the user roles.

To create a user group and add user accounts, proceed as follows:

1 In the User Rights Management area right-click on the User Groups main menu and click on Create new user group.

2 A name for the new group can be entered in the User Group dialog box.

3 Click on OK to add user group to User Groups list.

4 Open the All Users main menu and drag the desired user account into the appropriate user group sub-menu. The user is added to the user group and receives all access rights assigned to this group. A user can be added to one or more user groups.

■

10.1.4. Editing and Deleting User Accounts

The first name, last name and username of a user account can be edited if, for example, an existing user is to be replaced by a new user with identical access rights. A user account can also be deleted in the editing area.

Proceed as follows to edit a user account:

1 Click on User and Rights Management. The User Rights Management dialog box appears.

2 Open the All Users main menu and right-click the user account menu to be edited.

3 Click on Edit the user and the User Account dialog box appears. The name, last name, username, password and priority can be changed.

4 Click on the Deleted checkbox if the user account is to be deleted.

5 Click on Save to store the changes.

■

In order to avoid confusion, the Software will not allow for the creation of a new user with the same user name as a user name that has been deleted. Measurements that have been run under a user name that has been deleted are still available for viewing.



105Software

CC

10.1.5. Creating and Editing User Roles

Rights are generalized in user roles that comprise a single access right or a set of access rights. In the User Rights Management dialog box, access rights are called functions.

It is necessary to determine the different responsibilities for the different roles and, therefore, functions they should have access to.

Five standard user roles are pre-installed by the Software. All of the roles are suggested roles that could be used for setting up specific distribution of access rights:

c Administrator: The Administrator is allowed to use all administrative functions of the system. He is not allowed to use any operational functions.

c Production staff: It is intended for members of the Production Staff who are only allowed to use specific operational functions depending on company policies (i.e., execute measurements, execute an SST, change consumables).

c Research staff: Members of the Research Staff who could be allowed to use all operational functions of the system.

c Superuser: The Superuser is allowed to use all operational functions of the system, mainly for maintenance purposes.

c Support: Support of the Cedex HiRes System by Roche Technical Service requires access to all operational functions similar to the Superuser role.

Access to the System Options should be restricted to the Administrator, Superuser and Support. All options necessary for a user to modify his workplace according to his needs can be found under User Preferences.

Only selected users should be authorized to edit SST-Checkpoints. See “Creating SST Checkpoints” for further information.

Follow the instructions below to create a new user role:

1 In the User Rights Management dialog box, right-click on the All Roles main menu and then click on Create new role.

2 A name for the new role can be entered in the Role dialog box.

3 Click on OK to add the new user role to the All Roles list.

■

To add rights to or delete rights from an existing user role, proceed as follows:

1 Open the user role menu that is to be modified in the All Roles main menu. A Role Functions sub-menu will appear.

2 Open the All Functions main menu and drag the desired functions into the Role Functions sub-menu. These functions will be added to the user role. To delete certain functions from the User Role sub-menu, right-click on the desired function and select Remove the function from the role.

Composition rules

Min characters/Min digits Minimum requirements for the number of characters and digits used.

Min length/Max length Minimum and maximum length of the password.

Attempts to login Number of times wrong passwords can be entered consecutively before this user is denied access. Only the Administrator can reverse denial of access by issuing a new password. The user will be warned before the last allowed attempt.

Password…

never expires Passwords never lose their validity.

expires in Number of days after which passwords lose validity.

Warn the user Number of days before password expiration to warn the user.

Old password can be reused after Number of new passwords that must be used before an old password can be reused.

Use blacklist The so-called BlackList can be used to restrict selection of passwords to only those that fulfill a specific security standard. This list contains passwords that are not allowed to be used. The list is empty after installation of the Software by default.

The Administrator can enter incorrect passwords without limits with an extended time period after each retry.

10.2.2. Assigning New Passwords

Follow the instructions below:


2 Open the All Users main menu and right-click on the user account menu that is to be edited.

3 Click on Edit the user and the User Account dialog box appears.

10.3 Assigning Work AreasThe analysis results from a measurement are organized in work areas. A user needs to be assigned to at least one work area to be able to run a measurement, otherwise an error message will appear. All measurement data produced by this user will be saved in the work area selected during the execution of measurements. The user can only work with measurement data from work areas to which he has been assigned. New work areas can be created and assigned to one or more users via the User Rights Management area.

Follow the instructions below to create and delegate work areas:


2 In the All Users main menu, open the user account menu that is to be assigned the work area. A User Workareas sub-menu will become available.

3 Open the All Workareas main menu and drag the desired work area into the User Workareas sub-menu. This work area will be added to the user account.

■

To later deny access to a work area, follow the instructions below:

1 Open the User Workareas sub-menu in the user account that is to be modified.

2 Right-click on the work area that is to be removed and click on Remove the workarea from the user.


Assigning Work Areas


CC

10.4 The System OptionsThe System Options dialog box, in which system parameters are configured, is accessible via the Setup menu in the Cedex Control Center. Only those users who have been given access to the System Options function (for example the Superuser and Support) can change system parameters.

Setting system parameters includes several changes and modifications, some of which are explained in detail in the sections below. The parameters are organized based on the application areas that are affected (e.g., Measurement, Hardware, Data Exchange).

See “System Options and User Preferences” in the Appendix for a detailed description of all of the System Options.

The Cedex HiRes Software may need to be restarted in order for changes in the System Options to take effect.

All elements in the System Options that have not been explicitly described in this Operator’s Guide must not be changed without prior arrangement with Roche Diagnostics GmbH. In all cases, contact must be made with local Roche Technical Service before any such changes are made.

Access to the Systems Options should be restricted to only the users who are responsible for maintenance of the system. Changing default values in the Systems Options dialog box can have an adverse effect on the system and measurement results.

10.4.1. Automatically Start the Hardware Management

If the AutomaticallyStartHardware parameter is active (entry “1” in the Value column), the hardware management will automatically be initialized when the Software is started. To turn off this function, set the value to “0” in the Value column.

10.4.2. Modifying the Standard Setting for the Multi Sampler DefaultCup

The default setting for the Multi Sampler DefaultCup (Cedex Sample Cup used for Prime, LM ShutDown, focus calibration and all cleaning routines) is position 1 on the Multi Sample Tray. The default position can be changed to any other position. To change the position for the DefaultCup location, do the following:

1 Open the System Options dialog box and click on the General tab.

2 Look for the parameter DefaultCupPosition. The number entered in the Value column will determine the position for the DefaultCup on the Multi Sample Tray.

3 Click on Save to confirm the change.

■

The position chosen for the Multi Sampler DefaultCup does not influence measurements. All 20 positions on the Multi Sample Tray can be used for measurements. Should a sample be present in the DefaultCup position during Prime, LM ShutDown, calibration or any cleaning routines, it can no longer be used for measurements.


The System Options

109Software

CC

10.4.3. Turning off Automatic Incrementation of Sample Cup Position

In the case of single measurements run via the Measurement dialog box on a HiRes system with a Multi Sampler attached, the Software will automatically and incrementally increase the sample cup position number with each new measurement. To switch off this feature, do the following:

1 Open the Systems Options dialog box and click on the Measurement tab.

2 Look for the parameter SuggestNextCupPosition.

3 Select 0 from the drop-down menu to turn off the feature.

4 Click on Save to confirm the change.

■

When 0 has been selected, the suggested cup position will always be the same.

10.4.4. Turning off the Flow Chamber Prescan

Only cells that have settled down on the bottom of the chamber are well inside the focal plane of the scanner and, therefore, can be analyzed with an optimal image quality. A default sedimentation time of 60 or 90 seconds, depending on Cell Type, was selected to ensure that all of the cells from different cell types have settled down to the bottom of the flow chamber. Cells with larger diameters will generally settle to the bottom within 60 seconds. However, many cells with smaller diameters may require more time. Reducing the amount of time set for the sedimentation time will reduce the overall measurement time. Reducing the sedimentation time, however, is not standard procedure. A specific verification process is required to confirm the correct sedimentation time for a particular cell line. Local Roche Technical Service should be consulted for detailed information on the verification process.

During the sedimentation phase, a Prescan of the flow chamber is done and an image of the whole flow chamber delivered. If the sedimentation time is reduced to below 60 seconds, the flow chamber Prescan may need to be disabled since there may no longer be a sufficient amount of time for a Prescan to be taken.

To disable the Flow Chamber Prescan, do the following:

1 Open the System Options and click on the Measurement tab.

2 Look for the parameter MeasurementPrescanRequired. Enter 0 in the Value column to disable the Prescan.

3 Click on Save to store the change.

■

If the Prescan should be enabled again, re-enter 1 in the Value column of the parameter MeasurementPrescan-Required.

The Cedex HiRes Software requires one Prescan image to optimize the image brightness. It is necessary to ensure that at least one Trypan Blue-stained sample has been run on the system before switching off the Prescan feature.

The 60 second sedimentation time set by default for the Std. Size and Max. Size should generally allow enough time for a Prescan to be performed. In some cases of particularly slow computer systems, however, the Prescan may require slightly more time than the default sedimentation time. If this occurs, a message “Warning: sedimentation time was exceeded” will appear in the main Cedex Control Center. However, there will be no effect on the measurement other than slightly longer sedimentation time. The sedimentation time for the Std. Size and Max. Size can be increased, if desired, in order to have a sedimentation time that is longer than the Prescan time (see “Editing an Existing Cell Type”).


The System Options


CC

10.4.5. Error Level Displayed to Users

Errors in the Software and hardware will be displayed to the user in the form of an error message. The level of error that will result in the display of an error message depends on the setting of the parameter ErrorLevelDisplayToUser in the General tab of the System Options dialog box. The following levels are available:

c Level 1 (Fatal): fatal error, system/hardware crash,

c Level 2 (Critical): Error as a result of invalid measurement,

c Level 3 (Error): Error, but the result does not cause an invalid measurement,

c Level 4 (Warning): Information for user

If, for example, the ErrorLevelDisplayToUser is set at Level 1, only error messages regarding system or hardware crashes will be displayed to users. The factory-installed default for the ErrorLevelDisplayToUser is set at Level 3 (Error).

10.4.6. Liquid Container Configuration

In the Liquid Container Configuration area, the minimum and maximum liquid levels for reagent and waste containers can be set. To open the Liquid Container Configuration dialog box proceed as follows:

1 Click on the Master Data menu on the Cedex Control Center.

2 Click on Liquid Container Configuration and the dialog box appears.

■

Maximum and minimum volumes can be defined using this dialog box. When standard-sized containers are used, it is not advisable to change default settings for the Min volume and Max volume.

It is also possible to define a Warn Level and a Lock Level. The standard default for the Warn Level is 6. This means that a warning message will appear if the amount of reagents left is 6 ml or less. The standard setting for the Lock Level is 3, which means that the system will be locked (i.e., no further measurements will be possible) if there are only 3 ml left. The settings for the Warn Level and Lock Level can be changed. Saving changes will immediately update the estimation of the number of remaining measurements.

10.4.7. Disabling the Reagent Control

The Reagent Control function keeps track of the amount of reagents used and notifies the user when the levels are running low. The function can be disabled in the General tab of the System Options dialog box. The Reagent Control function is enabled when the value for the DisableReagentControl entry is set to “0”. To disable the function, set the value to “1”.

10.4.8. Default Settings

In general, Research or Production Staff users should not be assigned access rights to the System Options dialog box in which default settings that apply to the whole system can be configured. However, some parameters needed to customize the individual workplace (e.g., definition of the default settings for certain measurement parameters) can be found under User Preferences (see “User Preferences”).

10.5 Adjustment of the Image Analysis using the Live OperatorThe Cell Type (operator) selected for a measurement takes care of the image evaluation. For various application scenarios, Roche Diagnostics GmbH has put in three pre-settings that are adapted to a wide cell size spectrum:

c Min. Size for small cells with a diameter of about 6 μm, for example, lymphocytes, default sedimentation time is 90 seconds.

c Std. Size for normal-sized cells with a diameter of about 12 μm, for example, HB58, default sedimentation time is 60 seconds.

c Max. Size for large cells of more than 16 μm, for example, K-562, default sedimentation time is 60 seconds.

A Cell Type option, llumination Test, may also be available. This Cell Type is designed for service purposes only and is not intended for analysis of cells. The parameters for this Cell Type should not be changed!

The Cell Types may have slightly different names if the system has been upgraded from some previous version to Software version 2.3.2. In the case of a system that has been upgraded to version 2.3.2, the default sedimentation time for all Cell Types may be 90 seconds. Sedimentation time can be adjusted via the Cell Type List dialog box as described below.

Individual adjustments of the operator can be helpful or necessary for cell cultures that, for instance, have an unusual optical appearance or for a counting strategy that deviates from the standard Cedex HiRes Software analysis (e.g., counting aggregates differently).

Adjustment of the operator is referred to as creating a new Cell Type. A new Cell Type can be created or an already existing Cell Type can be re-adjusted. This can be done with the help of ten parameters that influence the way in which an image is evaluated.

Each of these parameters directly influences the image processing strategy and, hence, the measurement results. In the available Software version, an algorithm with the three pre-settings mentioned above is available. The parameters of the three factory installed pre-settings are overwritable.

For data safety reasons the parameters of the three factory installed pre-settings should not be altered. Since original settings are overwritable, caution should to be advised for all authorized users.

CC

10.5.3. Creating a New Cell Type

A new Cell Type must be created and saved via the Cell Type dialog box before the Live Operator dialog box can be opened for modification of that Cell Type.

Proceed as follows:

1 Open the Cell Type List dialog box. Highlight the existing Cell Type upon which the new Cell Type should be based.


2 Click on the NEW button. A message will appear asking if the new Cell Type should be based on the highlighted Cell Type in the list. Click on YES. The Cell Type dialog box will open. The LIVE OPERATOR button will be inactive at this time.

3 Fill in the information for:

c The name of the new Cell Type

c Sample preparation procedure (FVM is currently the only option)

c Focus Offset: the offset from the ideal focus point

The Focus Offset should be set to -25 to ensure best results for cell count and determination of viability. Please consult the local Roche Technical Service before using any other number for the Focus Offset, as selecting another value for this parameter may lead to poor results.

c Sedimentation Duration: the amount of time the cells are allowed to settle before chamber is scanned

The default value for the Sedimentation Duration is 90 or 60 seconds, depending on the Cell Type. This can be shortened depending on the Cell Type. Please consult with local Roche Technical Service before choosing other sedimentation times. Roche support will provide instructions for optimizing sedimentation times for specific cell lines.

4 Make sure that the IR Operator is set to CXHiResImageOperator.

Do not select either the IR Operator DBDMOperator or the IR Operator IlluminationTestImageOperator, if they are available. These IR Operators are designed for service purposes only and are not intended for analysis of cells. The parameters for these Operators should not be changed!

5 Click on the SAVE button. The Cell Type dialog box will automatically close. The Cell Type List dialog box will be active again and include the just-created Cell Type in the list.

6 Highlight the row of the new Cell Type and click on the EDIT button. The Cell Type dialog box will reopen and the LIVE OPERATOR button will be active.

7 Click on the LIVE OPERATOR button and the Live Operator dialog box will open (see Figure 115).

8 In the Data Source area, select the Work Area, followed by the Reactor ID, Sample ID and Data Set of the measurement for which the image analysis should be improved. The parameters for the loaded measurement are preset.

9 Select an image of the measurement in the Image ID section. This image will be loaded and displayed in the dialog box in the upper right-hand corner with the living cells marked with a green circle and the dead cells marked with a red circle.

10 Make the desired modifications on a single parameter first. As soon as a parameter has been modified, reprocessing of the data is automatic (see “Description of the Individual Operator Parameters”). The image display then shows the reprocessed image (see “Working with the Live Operator”).

11 When an optimized adjustment of the Operator parameters has been found, click on SAVE to confirm the modification for the new Cell Type.

12 Click on CANCEL to close the Live Operator dialog box without saving the changes.

■

Detailed step-by-step instructions for creating new Cell Types is provided in the Cedex HiRes Analyzer User Training Guide in Section C, “Analyzing Unusual Cells”.

The Cell Types may have somewhat different sedimentation times if the system has been upgraded from some previous version to Software version 2.3.2. Sedimentation time can be adjusted via the Cell Type List dialog box (see Section C, “Analyzing Unusual Cells” in the Cedex HiRes User Training Guide).




CC

60 second sedimentation time set by default for the Std. Size and Max. Size may not allow enough time for a Prescan to be performed. In some cases of slow computer systems, the Prescan may require slightly more time than the default sedimentation time. If this occurs, a message “Warning: sedimentation time was exceeded” will appear in the main Cedex Control Center. However, there will be no effect on the measurement procedure other than a slightly longer sedimentation time. The sedimentation time can be increased for the Std. Size and Max. Size, if desired, in order ensure a sedimentation time that is longer than the Prescan time (see “Editing an Existing Cell Type”). Alternatively, the Prescan function can be turned off (see “Turning off the Flow Chamber Prescan”, in the Cedex HiRes Analyzer Operator’s Guide).

10.5.4. Editing an Existing Cell Type

An existing Cell Type can be modified. However, it is NOT advisable for data safety reasons to modify an existing Cell Type that has been used for measurements. A new Cell Type based on an existing Cell Type should be created instead.

Follow the instructions below to modify an existing Cell Type (not advisable!):

1 Select the Cell Type to be edited from the list of Cell Types at the top of the Cell Type List dialog box and then click on the EDIT button. The Cell Type dialog box will open.

2 Modify the following information if desired:

c The name of the Cell Type

c Sample preparation procedure (FVM is currently the only option)

c Focus Offset

c Sedimentation Duration

3 Ensure that the IR Operator is set to CXHiResImageOperator.

Do not select either the IR Operator DBDMOperator or the IR Operator IlluminationTestImageOp-erator, if they are available. These IR Operators are designed for service purposes only and are not intended for analysis of cells. The parameters for these Operators should not be changed!

After loading a measurement by choosing the Reactor ID and Sample ID, and selecting an image, the selected image is displayed in the upper right-hand corner of the Live Operator dialog box. Each single cell detected by the Cedex HiRes Analyzer is marked as dead (red circle) or living (green circle).

Figure 116: Setting parameters for Cell Type Standard Cells

In the Process Data area, the values for new and previous results are displayed for viable cells (the number of living cells of the current image), dead cells (the number of dead cells of the current image) and %viability.

If an Operator parameter is modified, the newest values will appear under the New column when an automatic reprocessing of the selected image is finished. The values of the previous processing are displayed under the Previous column. Thus, direct comparison to each previous evaluation is possible.

The labeling of the cells can be switched on and off in the upper right-hand corner in order to allow for better evaluation of the results from changes in parameter settings. If multiple parameter changes should be made at the same time, remove the checkmark in the Automatic process box by clicking on it. When the checkmark is removed, the button PROCESS NOW becomes active. Make all changes, then click on the PROCESS NOW button for an analysis based on the new parameter settings.

10.5.8. Description of the Individual Operator Parameters

ClassificationBiasRange: [-20, 20], Default: 0, Unit: [absolute value].

This parameter influences the classification behavior of viable and dead cells. Since dying cells of different cell lines absorb Trypan Blue differently, dead cells can be variably stained. Positive values of this parameter tend to let the operator recognize more living cells and less dead cells. Negative values cause the opposite effect, with more dead cells and less living cells being recognized. This parameter’s default setting is optimized for dark-looking dead cells and living cells with a bright cell interior.

An example of a possible need for a change to a more negative value would be a cell line that poorly absorbs Trypan Blue when dead or dying. In the default setting with the value 0, these cells would still often be recognized as living. If the value is changed to negative value, however, more dark objects would be counted as dead cells. The viability recorded would, therefore, be reduced.

CMinSize. [µm] (Cells’ minimum size)Range: [0, 100], Default: 7, Unit: [micrometer]

This parameter determines the minimum cell size (diameter values measured in micrometer). It serves the purpose of discerning debris from cells.

LCAppearance (Live Cells’ Appearance)Range: [-10, 10], Default: 0, Unit: [absolute value]

This parameter influences the recognition of living cells. When the value of this parameter is set high, contrast-weak objects are also counted as living cells provided they additionally fulfill the size criterion. The lower this value is set, the more contrast an object must have for it to be counted as a viable cell.

If the value is changed to positive, shadowy and greyish objects are increasingly counted as living cells. Such a change can be sensible if, for example, the optical image shows little contrast due to the structure of the medium or of the cells in the medium.

DCAppearance (Dead Cells’ Appearance)Range: [-10, 10], Default 0, Unit [absolute measure]

This parameter influences the recognition of dead cells. If the value is set high, contrast-weak objects are also counted as dead cells as long as they additionally fulfill the size criterion. The lower this value is set, the sharper the contrast an object must have in order to be counted as a dead cell.

In standard situations, a change of this parameter can result in the labeling of debris as cells!




CC

CMaxSize [µm] (Cells’ Maximum Size) Range: [0, 100], Default: 70, Unit: [μm]

This parameter serves the purpose of setting the maximum cell size (diameter in micrometer) used for considering objects for evaluation. It distinguishes large dirt particles from cells.

AggrMinSize [µm] (Aggregate Minimum Size) Range: [8, 50], Default: 12 or 15 depending on Cell Type, Unit: [μm]

The minimum size of the region that should be analyzed as an aggregate is given here.

BorderWidth [pixel] Range: [0, 1000], Default: 10,Unit: [pixel]

The border frame around the image not used for evaluation.

The Borderwidth should not be adjusted in general. Consult with Roche Technical Service before making any adjustments to this parameter.

AggrMaxSize [µm] (Aggregate Maximum Size) Range: [10, 200], Default: 100, Unit: [μm]

The maximum size of the region that should be analyzed as an aggregate is given here.

LCAggrApp (Live Cells’ Aggregate Appearance) Range: [-10, 10], Default: 0, Unit: [Absolute value]

This parameter influences the recognition of living cells in aggregates. The higher this value is set, the more living cells are recognized in aggregates. The lower this value is set, the fewer living cells that are recognized in aggregates.

DCAggrApp (Dead Cells’ Aggregate Appearance) Range: [-10, 10], Default: 0, Unit: [Absolute value]

This parameter influences the recognition of dead cells in aggregates. The higher this value is set, the more dead cells are recognized in aggregates. The lower this value is set, the fewer dead cells that are recognized in aggregates.

MinPollutionArea [µm] (Minimum Pollution Area) Range: [50, 1000], Default: 100, Unit: [μm]

This parameter determines when an image will not be analyzed (i.e., the size [diameter in micrometer]), that an object (e.g., dirt or bubbles) must have for an image to no longer be analyzed is given here.

The use of the sliders, especially in combination, can lead to unexpected results.

10.6 Archiving DataThe objective of the archive function is to secure measurement data for future reference by exporting it to external storage media. Measurement data must be secured at regular intervals and thereafter deleted from the Measurement List in order to ensure enough storage capacity on the Cedex HiRes Control Unit. All data from a single or a set of measurements, or optionally only the images, can be deleted from the database (DB) once the measurement or measurements have been archived.

Archiving should only be carried out by the Administrator and selected users.

Measurement data can later be restored from the archive, but restoring the data is only possible using the Cedex HiRes System database from which the data has been archived.

Measurement data cannot be archived from one Cedex Software 2.3.2 DB and restored to a different Cedex Software 2.3.2 DB. The Data Exchange (Import/Export) function must be used when the intention is to import measurement data into a different DB. See “Data Exchange”, for more information about the Data Exchange function.

All data should also be backed up on a regular basis. Archiving does not replace a back-up strategy. Back-ups of the database should be carried out on a regular basis. See “Backing up the Database”, for more information.


Archiving Data


CC

10.6.1. Archive

To archive measurement data, proceed as follows:

1 Open the Functions menu in the Control Center and select the Archive function found within the Archiving menu.

A Measurement List dialog box appears with an ARCHIVE button at the bottom of the dialog box:

Figure 117

2 Select a single measurement from the list by clicking on the field on the left of the appropriate line, or choose a set of measurements by holding down the <Ctrl> button and selecting the appropriate lines. Alternatively, search for desired measurements using filter criteria.

3 After measurements have been selected, click on the ARCHIVE button.

The Archive dialog box opens:

Figure 118

4 Enter the path under which the archive files should be stored in the Location area. Alternatively, the button on the right of the entry field opens Windows Explorer in which the path can be selected directly.

Roche recommends ensuring that the target directory (location for the archived files) is empty in order to prevent possible unintended overwriting of critical files, which may result in data loss.

5 Click on Save. The Archive dialog box reappears.

6 (Optional) If desired, choose one of the following options in the Archive dialog box:

c Delete records: selecting this option results in measurements, including all respective images, being simultaneously archived to the selected target location and deleted entirely from the local Cedex HiRes database.

c Delete only images: selecting this option results in the selected measurements, including all respective images, being simultaneously archived to the selected target location while only images are deleted from the local Cedex HiRes database.

If no checkmark is placed in either box, measurements will be archived and simultaneously retained in the local Cedex HiRes Software database.

7 Click on the ARCHIVE button to start the archiving process. A message appears as soon as archiving of information is completed successfully. Click on OK.

8 Click on to close the Archive dialog box.

Three files are generated for each archived measurement package and stored in the selected location:

c CX2 file

c SIG file

c Text document

Figure 119

All three files are required for restoring the measurement package back into the Cedex HiRes Software DB. Ensure that all three files are always stored in the same location to enable restoring of measurement packages in the future.

■

A default entry for the path under which the archive file should be stored, can be entered in the System Options function under the Setup menu. Open the Data Exchange tab in the Systems Options dialog box and look for the ArchivePath parameter. In the Value column, enter the default path.

The following message may appear after selecting the measurements to be archived and clicking on the Archive button:

Figure 120

If this message appears, click on ‘YES’ to confirm the message and install the certificate. The archive will continue after confirming the installation of the certificate.

CC

10.6.2. Restore

To restore measurement data, follow the instructions below:

1 Ensure that all three files generated when the measurement package was archived are placed in the same folder (see “Archive”):

c CX2 file

c SIG file

c Text document

2 Select the Archiving option in the Functions menu on the Cedex Control Center and choose the option Restore.

The Restore dialog box appears, with ADD and REMOVE buttons located on the right-hand side of the dialog box:

10.6.3. Deleting Archived Data

Only data that has been archived can be deleted from the Cedex HiRes System database. Archived data still located in the database can be searched for and displayed in the upper right-hand corner of the Measurement List dialog box.

Figure 124: Measurement List dialog box with archived measurement shown

To delete archived data, do the following:

1 Click on the Archived measurements(s) checkbox in the upper right-hand corner of the Measurement List dialog box.

2 Click on FIND to display archived measurements. Highlight measurements to be deleted by clicking on the field on the left of the appropriate line. When choosing a set of measurements, hold the <Ctrl> button down while selecting the appropriate lines.

3 Click the checkbox beside Delete records if all measurement data is to be deleted from the system database. If the option Delete only images is chosen, all data apart from the images will stay in the system database.

4 Click on the DELETE button to delete selected measurements from the database.

CC

10.6.4. Reducing the Size of the Database after Archiving Data

The Archive function does not decrease the size of the database file after archiving measurements, even if the checkbox to delete the measurements and images has been selected. The space where deleted data was removed is only assigned to be overwritten by future measurement data. Therefore, the size of the database file will remain the same until the assigned database space has been filled with new data.

Since a large database may cause the Cedex Software to slow down, the database file size should be reduced if the size of the file exceeds 10 GB. Reduce the database file size with the use of the CX2_backup.bat and CX2_restore.bat batch files located on the Cedex Software 2.3.2 installation CD in the folder User Additional Features\Reducing the Database File Size. Step-by-Step instructions for this procedure, “Reducing Cedex Database File Size“ is located in the folder User Additional Features\Reducing the Database File Size.

10.7 Backing up the DatabaseIn addition to the complete measurement data (including the images), the database contains also the entries for the System Options and User Preferences. A backup system should be implemented to avoid any loss of data in case of a computer failure and to allow access to measurement results after a long period of time. A backup creates a copy of the current database on a second medium that then exists in addition to the original database. Creating a backup copy enables restoration of the database with the copy in case of data loss or corruption of the original database. This is especially useful for the full restoration of a system (e.g., crash recovery).

10.7.1. Basic Backup of the Database

The easiest way to back up the Cedex Software 2.3.2 database is to copy the complete database file, Cedex.fdb, to a different medium (e.g., portable hard drive, network etc.) at regular intervals. In case of a crash, after the necessary reinstallation of the Software, the database file can simply be replaced by the backup.

To create a backup of the Cedex Software 2.3.2 database, do the following:

1 Shut down the Cedex Client and Cedex Server.

2 Open Windows Explorer.

3 Navigate to the C:\folder and select the folder Cedex2 (default path C:\Cedex2). Press <Ctrl+C> (Copy) to copy the complete C:\Cedex2 folder, which contains the database file (Cedex.fdb).

4 Navigate to the external hard drive, network share, etc. where the backup should be stored.

5 Press <Ctrl+V> (Paste) to initiate copying of the Cedex2 folder to the new location.

6 Wait until the copying process has been completed successfully. This may take several hours, depending on the size of the database.

■

10.7.2. Incremental Backup of the Database

Because the basic backup method may be time-consuming and use a lot of memory space, Roche recommends an incremental backup procedure. An incremental backup is a method whereby multiple backups are kept. The backups are incremental in the sense that each original piece of backed up information is stored only once, and successive backups only contain the information that has changed since a previous backup.

An incremental backup can be created with a tool available for the Firebird DBMS - Database Management System, nbackup, located on the Cedex Software 2.3.2 installation CD. More information about the nback-up tool, is provided in the file “nbackup_firebird back up” located in the folder “User Additional Features\Backing up the Database” on the Cedex Software 2.3.2 installation CD.

125Maintenance and Care

DD

D Maintenance and Care

The Analyzer should be regularly serviced to guarantee optimal performance and maximize the life span of the Cedex HiRes Analyzer.

This includes the following maintenance procedures:

c Recurrent manual maintenance and cleaning routines when necessary.

c Cleaning routines with the Liquid Management.

c Cleaning and maintenance of the syringe module.

c Maintenance of the capillary tubes.

c Maintenance of the flow chamber, the scanner and the 8-way valve. This maintenance routine must be carried out only by an authorized Cedex HiRes System service technician.

This section provides detailed instructions and guidelines for each individual cleaning and maintenance procedure.


DD

1 Cleaning and Maintenance ChecklistThis checklist provides information about when each cleaning and maintenance routine should be done.

Perform these routines on a daily basis:

c LM Shutdown: always after the last measurement and before the Cedex HiRes Analyzer shutdown.

If a Prime has been scheduled to be automatically run the next morning, the Hardware Management should not be shut down as a Prime can only be run when the Hardware Management is active (see “Scheduling Automatic Cleaning Routines”).

c Standard Clean: after the final measurement of a set of samples or before a longer pause between measurements.

c Chamber Clean 2: at least twice per day.

Carry out this routine on a weekly basis:

c Intensive Clean

c Change of Trypan Blue solution

The following routine should be done every week for users that refill reagents themselves:

c Empty the reagent containers and the waste container.

c Thoroughly clean the containers.

c Refill the reagent containers (see “Refilling Containers Individually”).

Carry out this routine twice per month:

c Special Intensive Clean: at least twice a month with 0.1 – 1 N HCl instead of detergent.

Carry out these routines on a regular basis (once a week or after 250 measurements):

c Clean the casing, Reagent Tray, Multi Sampler housing (if installed) and Reagent Port by wiping down with 70% alcohol and a lint-free cloth.

c Run a focus adjustment of the Analyzer every month or after any change of position or vibration of the measurement system.

In order to ensure that the Cedex HiRes Analyzer is fully operational, an Intensive Clean must be carried out once per week even if the system is not being used for measurements.

Cleaning and Maintenance Checklist


DD

2 The Multi Sampler DefaultCupA Cedex Sample Cup is required for performing liquid management routines, such as Prime, LM Shutdown, calibration, and cleaning routines. The position of the Cedex Sample Cup used for all liquid management routines is called the DefaultCup position. The standard (default) position for the DefaultCup is position 1 of the Multi Sample Tray. The DefaultCup position can be changed (see “Modifying the Standard Setting for the Multi Sampler DefaultCup”).

The position does not influence measurements; all 20 positions on the Multi Sample Tray can be used for measurements. However, if a sample is present in a Cedex Sample cup placed in the DefaultCup position during a Prime, LM Shutdown, focus adjustment, or any cleaning routines, it can no longer be used for a measurement.

Place an empty Cedex Sample Cup into the position set for the DefaultCup before running LM Shutdown, focus adjustment, Prime, and all cleaning routines.



DD

3 The Hardware Management Dialog BoxPrime and LM Shutdown are executed in the Hardware Management dialog box.

A HW Startup initializes hardware interfaces such as the scanner, Multi Sampler, and pump. If a measurement is attempted before the Hardware Management has been started, an error message appears, “Cannot start a new process: Hardware Management is not started”. The Software automatically performs a HW Startup when launched if the Administrator has set this up in the system options (see “Automatically Start the Hardware Management”).

A Prime fills the capillary tubes and an 8-way valve with the appropriate reagents. If a measurement is attempted before the machine has been primed, an error message appears, “Cannot start new process: system is not primed”.

To perform a Prime, do the following:

1 Click the HWM button in the Cedex Control Center or select Hardware Management under the Functions menu.

The Hardware Management dialog box opens:

Figure 125

2 (optional) If the Hardware Management has not been started, the message “HW not started and LM not primed” appears in the current status field.

Click on the HW STARTUP button to start the hardware management if this message appears.

3 Ensure that a Cedex HiRes Reagent Kit is installed (see “Installing or Changing the Reagent Kit”) and a clean, empty Cedex Sample Cup is correctly positioned on the Multi Sample Tray in the DefaultCup position or attached to the single sample port.

4 Click the PRIME button in the Hardware Management dialog box. The duration of a Prime procedure is displayed in the Estimated total time area. The message “HW started and LM primed” appears in the current status field when the Prime is completed.


There should not be a break of more than 2 hours between a Prime and a measurement. If more than 2 hours have passed since the last measurement, a new Prime must be performed.

■

The Hardware Management Dialog Box


DD

An LM Shutdown must be performed after the last measurement has been run at the end of the day and before shutting down the Cedex HiRes Software. The Liquid Management system is then prepared for an extended pause, such as overnight or on the weekend.

An LM Shutdown is automatically preceded by a Standard Clean routine. The 8-way valve is then rinsed with distilled or deionized water to prevent crystallization, and compressed air finally presses the Trypan Blue solution back into its container.

To perform an LM Shutdown and (optional) a HW Shutdown:

1 Click the HWM button in the Cedex Control Center or select Hardware Management under the Functions menu.

The Hardware Management dialog box opens.

2 Ensure that a Reagent Kit is installed and a clean, empty Cedex Sample Cup is correctly positioned on the Multi Sample Tray in the DefaultCup position or attached to the single sample port.

3 Click the LM SHUTDOWN button in the Hardware Management dialog box. The duration of a LM Shutdown procedure is displayed in the Estimated total time area.

The message “HW started and LM not primed” appears in the current status field when the LM Shutdown is completed.

4 (optional) Click the HW SHUTDOWN button to shut down the hardware management. The message “HW not started and LM not primed” appears in the current status field when the HW Shutdown is completed.

■

4.2 Refilling Containers IndividuallyTo ensure optimal performance, the reagents must be free of impurities such as dust, crystals, biological material, or fluff. The Roche Cedex HiRes Reagent Kit guarantees optimal handling with the best possible safety. One Reagent Kit pack is sufficient for approximately100 measurements, including the standard cleaning routines.

Reagents can be refilled, or emptied in the case of waste, on an individual basis.

If you are using your own reagents, it may be necessary to filter them before use. Roche Diagnostics recommends using the Cedex HiRes Reagent Kit.

1 Thoroughly clean each Reagent Kit container before refilling to avoid impurities such as dust and fluff or contamination with microorganisms, to ensure optimal functioning of the Analyzer.

2 Fill the detergent container to the required level with Cedex Detergent (see label).

Only Cedex Detergent should be used for the cleaning procedures in order to prevent damage to the sensitive surface of the Liquid Management components.

3 Fill Cedex Cleaning Solution in the Cleaning Solution container to the required level (see label).

4 Fill distilled or deionized water in the water container to the required level (see label).

5 Fill 0.2% Cedex Trypan Blue solution in the Trypan Blue container to the required level (see label).

Roche Diagnostics recommends using 0.2% Cedex Trypan Blue Solution. If necessary, dilute a more concentrated Trypan Blue solution with buffer (Phosphate Buffered Saline (PBS), pH 7.4).

6 Place all of the reagent containers, as well as the emptied waste container, in the appropriate positions in the Reagent Tray.

Confirm each change individually by clicking on the respective SET FULL button or EMPTY button, in the case of waste, in the Reagent Kit Status dialog box.

7 Place a clean Cedex Sample Cup in the DefaultCup position on the Multi Sample Tray or attach it to the single sample port and perform a Prime (see “The Hardware Management Dialog Box”).

■


Refilling Containers Individually


DD

If the Trypan Blue is completely used up during measurements and then refilled, a Prime must be performed again before running the next sample (see “The Hardware Management Dialog Box”). If a Prime is not performed, the Prescan of the first measurement after refilling of Trypan Blue will fail and the measurement will be considered invalid (there will be no check in the ‘Valid’ checkbox found in the Measurement dialog box (see “Viewing the Prescan Image”). Subsequent measurements will be valid.

For reliable functioning of the reagent control (correct number of possible measurements, or reporting an impending overflow of the waste container), ensure that all reagent containers are correctly filled to the line with the appropriate liquid or, in the case of the waste container, completely emptied.

Confirm the changing of the reagents in the Software as soon as the Reagent Tray has been put back into the chamber. Failure to do all of the above will result in a mismatch between the calculated reagents available as shown in the Reagent Control and the actual reagent amounts in the containers or space available in the waste container.

The reagent control function that monitors reagent and waste levels can be turned off. See “Disabling the Reagent Control”.

Cleaning the reagent containers when manually refilling

All reagent containers must be thoroughly cleaned at regular intervals and rinsed with distilled or deionized water. Impurities caused by dust or fluff must absolutely be avoided! The Trypan Blue is especially critical as it can become contaminated with microorganisms. In the case of such contamination, exact measurements are no longer possible. If the Trypan Blue solution is contaminated, intense areas may be visible in the image that will make image analysis difficult or even impossible. Replacing the reagents after 5 days is recommended.

Checking the reagent containers when manually refilling

Empty reagent containers lead to wrong measurement results and can cause a dry run, thereby damaging the syringe and the 8-way valve. Regular checks of the liquid level are done via the Reagent Kit Status dialog box.

For safety reasons, the liquid level of the individual reagent containers, as well as the capillary positions, should also be manually checked before each measurement and, if necessary, replaced or refilled.

5 Scheduling Automatic Cleaning RoutinesRoutine cleaning operations can be scheduled so that they are automatically included in the process queue. Depending on the settings, the cleaning operations are automatically run at a pre-defined time or after certain events.

To create a new entry in the schedule, proceed as follows:

1 Select Scheduling from the Functions menu in the Cedex Control Center. The Schedule dialog box will appear.

2 Click on NEW to open the Schedule Process dialog box.

3 Select the Process that is to be included in the schedule from the drop-down menu at the top of the dialog box. The available processes include both cleaning routines (e.g., Fast Clean) and Hardware Management routines (e.g., Prime, LM Shutdown).

4 Select one of the three options with regard to the time schedule for an automatic process:

c Every: The process is automatically run at the selected interval of one or more days. A specific time of the day for operation can also be set.

c After an event: The process is automatically run after system startup or after a selectable number of measurements.

c After certain time of Inactivity: A certain amount of time of inactivity can be defined after which the process is run automatically. If the only once box is checked, the scheduled process will only be run once, even if there is another period of inactivity afterwards.

5 Click on SAVE to add the entry to the Schedule list. The Schedule Process dialog box will automatically close and the Schedule dialog box will reappear showing the newly scheduled process in the list.

■

Scheduled processes can also be edited and deleted by highlighting the appropriate row in the Schedule dialog box and then clicking on the EDIT or DELETE buttons. Clicking on the EDIT button will open the Schedule Process dialog box in which the process can be edited.

If Prime, LM Shutdown or routine cleaning routines have been scheduled via the scheduler, the Software application must be left on and the HW must be started. Prime and LM Shutdown can only be executed if the Hardware Management is active.

If an automated cleaning has been scheduled via the Scheduler function, the cleaning routine has a lower priority than scheduled measurements and is added to the process queue after all activated (status: active or scheduled) measurements have been carried out.

Note that measurement information placed in the Multi Run preparation area that has the status of edit is not added to the queue. Therefore, if a Cedex Sample Cup containing a sample is added to the Multi Sample Tray in the DefaultCup position, and the row for that sample is left in edit mode, the cup will be used for a cleaning routine should one be scheduled to be carried out at that time. Ensure that a Cedex Sample Cup containing a sample to be measured is never placed in the DefaultCup position on the Multi Sample Tray and left in edit mode during a Multi Run. Samples placed in the DefaultCup position for measurement should be immediately set to active or scheduled in order to be added to the process queue and, thus, have precedence over all scheduled cleaning routines.

6 Daily Maintenance and Cleaning RoutinesThe Liquid Management plays a key role in the Cedex HiRes Analyzer. It is necessary to Prime the system at the beginning of the day, and to carry out an LM Shutdown prior to shut down of the system in the evening (see “The Hardware Management Dialog Box”).

In addition, the Liquid Management automatically runs an Ultra Fast Clean routine after every sample measurement. During the Ultra Fast Clean (approx. 30 seconds), the entire Liquid Management system, including capillary tubes, flow chamber and sample port, are rinsed out thoroughly.

Manual cleaning routines can be performed in the Cleaning dialog box. To open the Cleaning dialog box, click on the CLEAN button in the Shortcuts area of the Cedex Control Center or select Cleaning routines in the Functions menu:

Figure 129: The Cleaning dialog box of the Analyzer

6.1 Cleaning OptionsThe following cleaning routines can be run manually:

c Fast Clean

c Standard Clean

c Intensive Clean

c Chamber Clean 1

c Chamber Clean 2

Fast Clean and Standard Clean involve the entire Liquid Management system including capillary tubes, flow chamber and sample port. Therefore, always ensure that there is a Cedex Sample Cup attached to the sample port or placed in the DefaultCup position on the Multi Sample Tray to prevent flooding.

Fast Clean (with detergent, and distilled water for approx. 60 seconds)

The entire Liquid Management system is rinsed with distilled water, then with detergent and finally with distilled water. Use this routine between measurements to remove dirt particles and air bubbles quickly from the flow chamber.

Daily Maintenance and Cleaning Routines

Cleaning Options


DD

Standard Clean (with cleaning solution, detergent, and distilled water for approx. 90 seconds)

The entire Liquid Management system is rinsed with distilled water, cleaning solution, detergent and finally with distilled water again. This routine removes dirt particles and is used after measuring a set of samples or before a longer pause.

Intensive Clean (with cleaning solution, detergent, and distilled water for approx. 20 minutes)

The flow chamber is thoroughly rinsed with distilled water, cleaning solution, distilled water, detergent and finally distilled water. The detergent remains in the flow chamber for a longer period to work on resistant particles.

The Intensive Clean routine is used on weekly basis to remove heavy and resistant contamination of the flow chamber, capillaries tubes, syringe and 8-way valve. Even the smallest dirt particle attached to the glass wall of the flow chamber can negatively influence a measurement. See also “Scanning the Chamber to Verify the Effectiveness of Cleaning Routines”. If measurement values within a sample measurement show large variations, this could indicate that the flow chamber is soiled.

Intensive Clean with HCl

A special Intensive Clean is required twice per month for a thorough cleaning. For this cleaning, a solution of 0.1 – 1 N HCl is used instead of detergent.


1 Remove the Detergent container and replace it with an appropriate container with a 0.1 – 1 N HCl solution, taking care that the capillary tube reaches far enough into the solution.

2 Start Prime.

3 Start Intensive Clean after Prime has ended.

4 Replace the HCl container with the Detergent container at the end of the Intensive Clean process.

5 Start Prime again.

6 Start Standard Clean after Prime has ended.

■

The Chamber Clean 1 and Chamber Clean 2 cleaning routines are only required for the flow chamber.

Chamber Clean 1 (with water for approx. 10 seconds)

The flow chamber is rinsed at high pressure with distilled or deionized water being drawn in through the syringe. Use this routine to remove resistant protein aggregates, fluff particles or other obstructions from the flow chamber.

Chamber Clean 2 (with water, detergent, and air for approx. 30 seconds)

This routine is more intense than the Chamber Clean 1 procedure. Once the flow chamber is rinsed with water and detergent, the remaining liquid in the capillary tubes between the syringe and valve head is drawn through the flow chamber and then pressed back again with compressed air.

Use this routine twice daily to remove resistant protein aggregates, fluff particles or other obstructions from the flow chamber.

LM Shutdown

During an LM Shutdown, all of the capillary tubes in the Liquid Management system are cleaned and rinsed with distilled or deionized water. In addition, the Trypan Blue is withdrawn from the 8-way valve/syringe and replaced with air. This is to prevent the capillary tubes and flow chamber from becoming damaged.

DD

6.2 Performing a Cleaning RoutineThe different cleaning routines always have the same starting procedure. Ensure that there is always a Cedex Sample Cup attached to the single sample port or a Cedex Sample Cup placed in the DefaultCup position of the Multi Sample Tray.


1 Click on the CLEAN button in the Shortcuts area of the Cedex Control Center or select Cleaning Routines in the Functions menu. The Cleaning dialog box will open.

2 Click on the appropriate button (e.g., FAST CLEAN) to automatically start the cleaning routine.

■

The Cedex HiRes Analyzer is blocked during the cleaning routine, and the duration is continuously displayed in the Estimated Total Time field.

6.3 Interrupting/Terminating a Cleaning RoutineUse the EMERGENCY STOP button to interrupt the cleaning routine immediately if any leaks are detected in the Liquid Management system, even in the case of an Ultra Fast Clean being carried out automatically.

The Intensive Clean procedure can be interrupted to shorten the long detergent phase in the flow chamber. Click on the CANCEL button, which is only activated during the long detergent phase, in the Liquid Management dialog box.

6.4 The Prescan FunctionDuring a measurement, the sample is injected into the chamber, and the cells are allowed to settle to the bottom of the flow chamber for a specified amount of time (the sedimentation phase). The system checks the flow chamber for impurities with a separate scan (Prescan) during the sedimentation phase. If the system detects impurities in the flow chamber, an error message, “Dirt or bubbles detected during Prescan!” appears. The measurement is completed and results calculated even if this error message appears. However, no check appears in the Valid checkbox below the Image area in the Measurement dialog box for that measurement.

If the error message appears, check the Prescan at the end of the measurement to see if it is acceptable or not (see “Viewing the Prescan Image”). If the flow chamber appears to have had dirt or impurities, then perform a Standard Clean before performing a new measurement (see “Performing a Cleaning Routine”). If the Prescan is acceptable, the measurement results can still be used.


Performing a Cleaning Routine


DD

6.5 Scanning the Chamber to Verify the Effectiveness of Cleaning RoutinesThe complete flow chamber can be scanned using the SCAN button in the Cleaning dialog box. Using this, the success of the cleaning can be verified after a cleaning routine.

Proceed as follows:

1 Click on the CLEAN button on the Cedex Control Center to open the Cleaning dialog box.

2 Click on the SCAN button in the lower right-hand corner of the Cleaning dialog box. The flow chamber will be scanned (i.e., an image of the entire chamber will be created). This process can take 1– 2 minutes during which the estimated time is displayed in the form of a progression bar.

■

The Current area displays the scanned image.

Since the flow chamber is represented as a whole, it is necessary to enlarge single regions (especially the inlet and outlet) with the help of the zoom function in order to be able to effectively check the chamber.

Enlarge certain areas of the scan by doing the following:



3 Release the mouse button and the selected area will fill the whole dialog box.

■

Return to the original size of the scan by following the instructions below:

1 Place the mouse pointer anywhere on the diagram.

2 Hold the left mouse button pressed down and form a box from the bottom right corner to the upper left corner.

3 Release the mouse button. The scan will then return to its original size.

■

The brightness and contrast of the image can also be changed for a better analysis.

If a previous cleaning routine was unsuccessful (i.e., if any (dirt) particles are visible in the Scan image), a new cleaning of the flow chamber must be done. Perform another scan to check this cleaning. The image created after this scan can be viewed in the Current area. The image taken previous to this scan can be seen in the Previous area.

7 Automatic Adjustment and Alignment VerificationThe automatic adjustment and verification of alignment adjusts the focus position of the flow chamber and verifies the alignment of the chamber itself to ensure that images of consistent quality are taken during measurements.

The service technician will perform a focus adjustment before the initial operation of the Cedex HiRes Analyzer. The focus adjustment is always necessary after the Analyzer has been moved. Additionally, we recommend running a focus adjustment once per month for control purposes. Both the white balance and the focus on the objects to be examined are optimally set during this focus adjustment. The focus adjustment lasts approximately 20 minutes and is done with the Cedex Calibration Beads.

If at all possible, the Analyzer should never be turned off. If it is necessary to turn it off, the Analyzer needs at least 2 hours to warm up before an Automatic Adjustment can be carried out.

Proceed as follows to do the focus adjustment:

1 Open the Functions menu in the Cedex Control Center’s menu bar.

2 Click on Automatic adjustment to open the Automatic Adjustment and Alignment Verification dialog box.

3 Pipet 1 ml of a well-mixed bead solution (Cedex Calibration Beads) into a Cedex Sample Cup.

4 Attach the Cedex Sample Cup to the sample port or place the Cedex Sample Cup in the DefaultCup position on the Multi Sample Tray (see “The Multi Sampler DefaultCup”).

5 Click on the START AUTOMATIC ADJUSTMENT button. You will be asked to verify that the beads have been prepared. Click on OK to confirm and start the adjustment process.

■

Figure 131: The Automatic Focus Adjustment dialog box after adjustment

Automatic Adjustment and Alignment Verification


DD

The automatic adjustment and verification of alignment is carried out in several steps. First, water is pumped into the flow chamber and a white balance is carried out. The Cedex Calibration Beads are then injected into the flow chamber. Focus finding occurs after sedimentation. An automatic cleaning of the flow chamber and the capillaries, as well as a new white balance, is done after focus adjustment. The focus adjustment’s time-progression is displayed as an estimated value in the form of a blue progression bar.

Scans are carried out for every focus position. The images of the four corner areas are analyzed and these focus values displayed in a diagram (see Figure 131). Focus positions are shown on the x-axis and focus quality on the y-axis. A measurement can only deliver optimal results if the flow chamber is scanned at one level. This means that the corner areas must have the same focus level.

The result appears on the monitor as a message box once the focus adjustment is finished (see Figure 131). Verify that the different positions of the flow chamber have the same focus position by checking against the conditions explained below, and confirm your approval with Yes.

The focus position automatically set for the four corner areas (optimal position) must lie between 850 and 1250. Otherwise, an authorized service technician must re-adjust the Cedex HiRes Analyzer. Another important value is the allowed maximum difference between the optimal focus values of the four corner areas. The focus difference must be between 0 and 20. Otherwise, an authorized service technician must re-adjust the Cedex HiRes Analyzer.

The Automatic Adjustment and Alignment Report can be printed out via the PRINT REPORT button. The report shows a diagram (Focus Chart) with four curve progressions to the focus position.

The quality of the automatic adjustment and verification of alignment depends on the pre-adjustment of the flow chamber and an even concentration of the focus beads in all of the pictures of the 4 corners. In order to check that these conditions have been fulfilled, the following must be verified:

c No edges are visible in the 4 pictures of the corners of the flow chamber.

c The pictures are not out of focus.

c All of the pictures have an even distribution of beads with at least 50 beads in every picture.

c The focus curves of all 4 corners have two clear maximums with one clear, marked minimum in the middle.

If any one of these conditions is not fulfilled, the results of the automatic focus adjustment should not be used!

Should striped shadows or lines appear on the images when running measurements, a new focus adjustment needs to be run as poor image quality can affect the results of the measurement.

8 Syringe Maintenance Moving parts of the Syringe Module may cause hand injuries. Never run a measurement on the Cedex

HiRes Analyzer without the protective cover for the Syringe Module in place. When performing a syringe maintenance, be aware of the risks from moving parts.

The flow chamber, tubes, syringe and 8-way valve are cleaned during the Intensive Clean routine (see “Cleaning Options”).

However, the syringe is subject to wear and tear and must, therefore, be regularly replaced to maximize the life span of the 8-way valve and to guarantee optimal performance. The syringe should be replaced approximately every 6 months under normal use of the Analyzer. More frequent use may require more frequent changing of the syringe.

To change the syringe, follow the steps specified in the sections below:

8.1 Removing the Syringe

1 Click on Syringe Maintenance in the Functions menu of the Cedex Control Center. The Syringe Maintenance dialog box will open (see Figure 132).

2 Click on the REMOVE SYRINGE button. The syringe barrel will be moved to a position to allow easy removal.

3 Remove the protective cover with the use of a Phillips head screwdriver. Turn the screws 90 degrees counter-clockwise to release the screws.

4 Hold the syringe barrel by the Luer lock and turn it counterclockwise to remove it from the 8-way valve (see Figure 133).

5 Once the connection is loosened, keep holding the syringe barrel in an upright position beneath the 8-way valve to prevent it from jamming with the plunger.

6 Remove the bottom screw that connects the plunger to the Syringe Module with the other hand.

7 Remove the syringe from the Syringe Module.

9 Maintenance of the Flow chamber, 8-Way Valve and the Remaining Hardware Components

To ensure that Cedex HiRes Analyzer functions uninterruptedly, maintenance work is necessary at regular intervals. An arrangement for a maintenance contract with your local Roche representative is recommended. During maintenance, worn out and defective components are replaced and the functioning of the Cedex HiRes Analyzer is checked.

Only an authorized service technician is permitted to carry out maintenance when the Cedex HiRes Analyzer needs to be opened!

10 Operational DataThe Cedex HiRes System keeps track of some operational data including operating hours, number of measurements and liquid consumption. Select Operational Data in the Functions menu of the Cedex Control Center to open the Operational Data dialog box.

The values on the left-hand side of the dialog box can be set to 0 by clicking on the RESET button. This can be useful for tracking the operational information for short periods of time. The values on the right-hand side track the overall operating hours, number of measurements and liquid consumption. These values cannot be reset.

A report of the operational data can be printed out via the PRINT REPORT button.

11 The System Suitability Test (SST)To ensure proper operation of the Cedex HiRes Analyzer and valid analysis results, it is essential that the system is in good condition. The majority of the critical parameters are regulated by design or preventive maintenance activities carried out by local Roche Technical Service. The routine checkups performed by the user of the Cedex HiRes Analyzer mainly focuses on the liquid management process (such as flow chamber, capillaries, etc.).

A feature of the Cedex HiRes Software 2.3, the System Suitability Test (SST), is designed to help monitor the state of the system for quality supervision/assurance purposes. A routine checkup procedure that meets the system owner’s specific needs can be created using the SST Software feature.

Verification that the Analyzer is in the required condition comprises both manual checks (internal as well as external scrutiny of the equipment, for example, hamber inspection) and various checkup and calibration measurements. These individual procedures are known as SST checkpoints. When an SST is set up on a Cedex HiRes Analyzer, checks and measurements will have to be performed on a regular basis. Passing the checkpoints will then be mandatory for normal continuation of measurement procedures.

The System Suitability Test consists of different types of SST checkpoints. Each checkpoint needs to be created and its parameters, including the acceptance criteria, need to be configured by an authorized user (the Superuser or Administrator). Once created and activated, the checkpoints apply to the whole system.

11.1 Creating SST CheckpointsThe System Suitability Test consists of different types of SST checkpoints. There are two main types of checkpoints: an SST requiring inspection or maintenance activity performed by the user (e.g., syringe change, chamber inspection) and SST procedures involving measurements with either Cedex HiRes Control Beads or Density Reference Standard Beads, available from Roche Diagnostics. In order to pass a checkpoint involving Beads measurements, the average result of a pre-defined number of one or more measurements needs to be valid according to the checkpoint criteria. A checkpoint requiring an inspection or maintenance activity demands an active confirmation in the System Suitability Test dialog box that the activity or inspection has been performed.

Each checkpoint needs to be created and its parameters, including the acceptance criteria, must be configured by an authorized user. For this, authorized users need to be assigned the SST edit function. Users who perform SST procedures only need access to the SST run function. Once created and activated, the checkpoints apply to the whole system.

On some systems, an inactive list of proposed SST checkpoints may be automatically provided in the System Suitability Test List dialog box. To activate these checkpoints, click in the box under the Active column for the checkpoint. A checkmark will appear in the Active column, which indicates that the checkpoint has been activated.

11.1.1. Creating SST Checkpoints with and without Measurements

To create a new SST checkpoint, proceed as follows:

1 Select SST in the Functions menu to access the System Suitability Test List dialog box, or click directly on the SST button in the Cedex Control Center.

2 Click on the NEW button and the System Suitability Test New dialog box will appear. Using this dialog box, a measurement checkpoint or a manual checkpoint can be created.

3 To create a checkpoint for a manual check or maintenance activity, click on the SST WITHOUT MEASUREMENT button. This will open the System Suitability Test New dialog box that allows for the creation of a checkpoint for a manual check. Enter an SST Name (e.g., Flow Chamber) and an SST Description that provides sufficient information for any user performing this SST.

4 To create checkpoints for calibration measurements, click on the SST INCLUDING MEASUREMENT button. The appropriate System Suitability Test New area will appear. A set of parameters needs to be defined. See Table 2, for a detailed description of the parameters.

5 Click on the SAVE button to create a new SST checkpoint. The checkpoint will be immediately added to the System Suitability Test List.

6 Clicking on SAVE will close the dialog box without creating an SST checkpoint.

■

Parameters for SST including Measurement:

SST Name/ SST Description

Enter an SST Name and Description for identification purposes during routine checkup procedures.

Overall Type Select the characteristic that is to be inspected during the measurements for this checkpoint (e.g., Total Cell Count, Total Concentration) from the drop-down list.

Cell Type/ Measurement Precision/Sample Volume/ Sample Initial Dilution

Define different measurement parameters for different checkpoints to verify operational reliability in various situations.

Target Value The Target Value serves as benchmark for the acceptance criteria. It can be based, for example, on the average result of a set of measurements carried out with Cedex HiRes Control Beads.

Offset The offset in % determines the acceptance range applicable to the results of SST measurements carried out for this checkpoint based on the target value entered.

Target Value Check/ Upper Limit/ Lower Limit

If the Target Value Check is activated, the user performing SST measurements can enter another target value before running the first SST measurement for this checkpoint (e.g., when a new container of Control Beads is used). Acceptable limits for what can be entered by a user for the variable target value are set using Upper Limit and Lower Limit fields.

The Upper Limit and Lower Limit fields are not related to the acceptable range for results from an SST measurement! The acceptable range for results is determined by the % entered in the Offset field.

Fixed Target Value If the target value is not entered by users, the Fixed Target Value must be activated.

Count For Passing Count for Passing refers to the number of SST measurements that has to be performed for this checkpoint.

Table 2: SST parameters for SST with Measurement

In general, the Target Value is determined before the SST checkpoint is activated. For further information on the procedure for the determination of a target value, Roche Technical Service provides appropriate recommendations. It is necessary to re-determine the target value if a new container of Cedex HiRes Control Beads is used.

An SST checkpoint includes a validity period. This can be set in the System Suitability Test List in the Days Valid column. After this period of time, the SST procedures must be performed. If the SST procedure is not performed within the validity period, all measurements apart from SST measurements may be prohibited (e.g., the system status is changed to MeasurementLock).




DD

11.1.2. Running a Water Blank

Before an SST including Measurement is run, a water blank (Water For Injection [WFI]) should be run to check the condition of the reagents. No more than 20 counts should be recorded for this measurement. This can be scheduled using the SST INCLUDING MEASUREMENT button (see “Creating SST checkpoints with and without measurements”). The WFI measurement requires a relative deviation rather than an absolute deviation, which means that 0 cannot be used as a Target Value, as a relative deviation from 0 will always be 0.

Therefore, when setting up a WFI measurement, the Target Value should be set to 10 with a relative deviation of 100%. This will result in an acceptance range of 0 – 20 objects (see Table 2).

11.1.3. Setting up the SSTFailureReaction in the System Options Menu

The reaction of the system to an SST failure depends on the configuration in the System Options. The System Options can be accessed under the Setup menu on the Cedex Control Center:

1 Open the System Options and click on the General tab.

2 Look for the parameter SSTFailureReaction.

c Entering Restrict in the Value column will lead to prohibition of any further measurements, including SST measurements, in the event of an SST failure. This will require a manual unlocking of the system in the Lock – Unlock System area before measurement activity can be resumed (see “Locking – Unlocking the System”).

c If Warning is entered, measurement activity can be continued but there will be a warning about SST failure before a measurement is carried out.

c Choosing the Audit option will simply lead to a log entry in the audit trail file in the case of an SST failure. There will not be any restrictions or warnings.

3 Click on Save to store the change.

■

Measurements that are run despite the fact that not all SST procedures are up to date or valid, will have no checkmark in the SST Valid box in the Measurement dialog box.




DD

11.2 Performing an SSTAll procedures related to the System Suitability Test can be controlled via the System Suitability Test List. To access the list, open the Functions menu in the Cedex Control Center and click on SST or directly click on the SST button in the Cedex Control Center.

The System Suitability Test List provides an overview of all SST checkpoints and their current status. Valid SST checkpoints are displayed in black while red indicates an invalid checkpoint. SST checkpoints should be performed at regular intervals; the length of these intervals is specified in the Days Valid column. To confirm a checkpoint, either manual checks have to be done or measurements need to be performed.

Checkpoints should be confirmed in the daily/weekly work routine and not to left until the validity period of a checkpoint has expired.

11.2.1. Performing an SST with Measurements

If the SST to be performed requires a measurement or series of measurements, do the following:

1 Select SST from the Functions menu on the Cedex Control Center. Alternatively, click on the SST button in the Shortcuts area of the Cedex Control Center. The System Suitability Test List dialog box will appear.

2 Select the SST checkpoint to be confirmed by clicking on the field to the left of the appropriate line.

3 Click on RUN SST to start the SST procedure. The System Suitability Test Measurement Run dialog box will appear. The parameter settings can be viewed but not altered.

4 Whether or not the Target Value can be changed depends on the configuration. If the Fixed Target Value option is not activated, the user will be able to change the target value. However, if the Target Value Check is activated, the user will have to enter a value within the defined limits (Upper Limit, Lower Limit).

5 Click on RUN to start the SST measurement. The Measurement dialog box will appear and the measurement will be carried out automatically.

6 Close the Measurement dialog box.

7 Repeat measurement as often as required for this checkpoint (see note below).

■

The Count For Passing value given in the System Suitability Test Measurement Run dialog box indicates the number of measurements that have to be carried out for a particular checkpoint. The average value will be calculated from all of the measurements required for a particular SST checkpoint.

The average value of all test measurements needs to be within the acceptance range. The acceptance range is defined by the target value and the offset (in %). In the event of an invalid SST measurement, the system will immediately be locked. Once in SSTLock, the system needs to be unlocked manually by authorized users before any further SST or other types of measurements can be carried out.

If the average result of all test measurements for an SST checkpoint is valid, the checkpoint will automatically be displayed in black.

11.4 Locking – Unlocking the SystemMeasurements that are carried out after the validity period of an SST checkpoint has expired are marked as invalid in the Audit Trail. In addition, the system may be locked for any further routine measurements except SST measurements.

The System Status describes the capability of the system for performing certain tasks involving the hardware. The current state of the system can be viewed in the Change System Status dialog box, which is accessed by selecting the Lock – Unlock System option in the System menu of the Cedex Control Center (see Figure 139).

The state of the system is set automatically depending on the validity of all SST checkpoints, and the configuration of the SSTFailureReaction parameter in the System Options. Depending on the configuration, if an SST checkpoint is out of date only SST measurements can be carried out. No routine measurements will be possible (Current State: MeasurementLock). Once all SST checkpoints are up to date and valid again, the system is fully usable and the Current State is automatically set to SystemOK.

In the event of a failed SST procedure, the system may be locked for any further measurements including SST measurements (this is only the case if the SSTFailureReaction parameter in the System Options is set on Restrict, see “Setting up the SSTFailureReaction in the System Options menu”). The Current State will be automatically set to SSTLock.

The system status can be changed manually by authorized users. Manually changing the system status may be necessary for a variety of reasons. For more details, see the following table:

Manually set System Status to:

E Troubleshooting

For technical support, the Roche service technician will require at least the following files:

c Diagnosis file (see Section E, Chapter 1)

c Cedex Log and Cedex Trace files (see Section E, Chapter 2)

c Audit Trail file (see Section E, Chapter 3)

c The 3 exported complete measurement file packages generated with the Data Exchange function (see “Export”) that show the issue.

1 Diagnosis of the Cedex HiRes AnalyzerFor technical support purposes, the user is able to run a diagnosis of the Cedex HiRes Analyzer at the request of a Roche authorized service technician. The diagnosis of the System provides a file containing information about the System Software and hardware. It contains a system description, hardware and Software descriptions (i.e., product name, version), parameters and settings (i.e., focus position, white/black balance).

To create the diagnosis file, follow the instructions below:

1 Click on the Setup menu on the Cedex Control Center.

2 Click on Diagnosis and the Diagnosis dialog box will appear.

3 The hardware to be included in the diagnosis can be selected by checking the appropriate boxes in the Hardware to diagnose area or by checking the box beside Diagnose all hardware. The diagnosis of the System Software is also optional and can be selected by checking the box beside Diagnose system software.

4 Click on START DIAGNOSIS to run the diagnosis of the Cedex HiRes Analyzer.

5 The diagnosis data can be saved by clicking on SAVE TO FILE and printed by clicking on PRINT DATA.

2 Trace and LoggingTrace and Logging are only required for support and problem detection purposes. Therefore, it is advisable to restrict access to Trace and Logging to the support team and users with extended permissions (e.g., the Superuser).

Trace and Logging functionalities should only be activated at the request of an authorized service technician.

In order to avoid an exaggerated use of hard disk space, turn off the Trace and Logging functionalities as soon as the issue has been located and/or resolved.

To activate or change Trace and Logging parameters, open the Setup menu in the Cedex Control Center. Clicking on Trace & Logging will open the corresponding dialog box.

The tracing functionality, as well as the logging functionality, can separately be enabled for individual modules of the Cedex HiRes Analyzer.

Tracing is in the Off state by default. The application has two Trace Levels. The first one (tracing level Normal) is used for minimal tracing required for time critical problems. The second level (tracing level Extended) is necessary for a more detailed problem description. To set the Trace Level, click on the current status and a drop-down menu will appear from which level can be selected. Logging is in True state by default.

Trace and log records are saved in files which are accessible by using Windows Explorer. The records are found in the C:\Cedex2 directory under Logs (CedexLogand_YYYY_MM_DD.log and CedexTrace_YYYY_MM_DD.log).

Target files for tracing and logging data can be defined in the System Options menu. These files will automatically be created in the Cedex2 folder. The data will then be stored in the default target files as well as the newly defined target files. Open the Tracing (Logging) tab and enter the desired target file path for the TraceOutputPath (LogOutputPath) parameter in the Value column.

3 The System Audit Trail FileAll user-initiated activities, as well as important actions carried out by the Cedex HiRes Software 2.3, are recorded in the Audit Trail file. The system also logs all errors in the audit trail, including information from the error message.

For each activity, the User, Measurement ID, Workarea Name, Reactor Identifier and Sample Identifier are given. The actions are classified by Event Types and a short message provides further explanation.

To support monitoring of user-initiated activities, a search filter is available that also allows for defining the period of time which is to be searched.

A report can be printed by clicking on PRINT REPORT.

1 System Options und User PreferencesThe following list provides a description of all of the Systems Options that can be found in the Cedex HiRes Software 2.3 via the Systems Options dialog box found under the Setup menu of the Cedex Control Center.

If an adjustable option exists in both the System Options dialog box and the User Preferences dialog box, the entries in the User Preferences dialog box take precedence over the entries found in the System Options. For example, if the default Cell Type in the System Options dialog box is “CT1”, but user “Joe” selected Cell Type “CT2” as the default in the User Preferences dialog box when he was logged in, the default Cell Type will be “CT2” when the user “Joe” is logged in. The defaults set in the System Options dialog box will apply to new users who have not set their own defaults in the User Preferences dialog box.

If the column SaveLastValue has been selected for a particular parameter (i.e., there is a cross in the column), any new value entered in the corresponding location will be automatically saved in the System Options or the User Preferences dialog boxes. For example, user “Joe” has set the default for the Cell Type in the Measurement section of his User Preferences dialog box to “CT1” and has activated the SaveLastValue option. If “Joe” changes the Cell Type parameter to “CT2” when running a new measurement, “CT2” will be automatically saved as the new default in his User Preferences dialog box and will be automatically recommended for the next measurement. The SaveLastValue function can be activated for all options in the System Options dialog box and for all options in the User Preferences dialog box for every individual user.

If the system has been upgraded from some previous version to Software version 2.3.2, it is possible that some default settings in the System Options may have slightly different values than those described in this manual. The settings described below apply to systems on which Software version 2.3.2 has been installed as the original Software.

Rows that are shaded blue in the list below indicate options that exist in both the Systems Options dialog box and the User Preferences dialog box.
