2) These parameters are not ready-to-use test kits. You will find all detailed information in our application list on

the Internet homepage http://photometry.merck.de. 4) Please see programming data under non-linear calibration or absorption-concentration- table. Remark: “own blank” means distilled water and all reagents in the same quantity as used for the measuring sample preparation. Separately prepared in standard test tubes and poured into the type of cell used. “cell with blank” means the white capped ready-to-use blank sample in cell tests for use with round cell measurement. The instrument must be equipped with a round cell holder. “dist. water” means distilled water without reagents and poured into the type of cell used. “clear sample without reag.” means sample must be colourless and turbid samples must be filtered.

Each test kit contains a package insert with detailed information regarding the standard procedure of the measurement. In some cases, however, special points have to be considered which are not mentioned in the package inserts. In this appendix you will find specific applications and modified methods for analyses for sensitive measurements indicated with a 1).

Calcium: with Spectroquant® Calcium Test, Cat. No. 1.14815.0001 Measuring range: 1.0 – 15.0 mg/l Ca 2.5 - 37.5 mg/l CaCO3 1.4 - 21.0 mg/l CaO Procedure: Add 10 ml of reagent Ca-1 and 8 drops each of reagent Ca-2 and Ca-3 to 1 ml of the sample solution and mix. Leave to stand for 8 min for colour development. After filling into 10 mm cells measure in the photometer at 550 nm. Prepare the blank required for the measurement according to the above-mentioned procedure using 1 ml of distilled water instead of the sample solution. Fluoride: with Spectroquant® Fluoride Cell Test, Cat. No. 1.14557.0001 Measuring range: 0.025 – 0.500 mg/l F-

Procedure: Pipette 10 ml of sample solution into the reaction cell, mix and add 1 blue microspoon of reagent F-1K. Close the cell tightly and dissolve the solid by shaking. Leave to stand for 5 min for colour development. After filling into 50 mm cells measure in the photometer at 620 nm. Prepare the blank required for the measurement according to the above-mentioned procedure using 10 ml of distilled water instead of the sample solution.



Sulfite: with Spectroquant® Sulfite Cell Test, Cat. No. 1.14394.0001 Measuring range: 0.005 – 3.00 mg/l SO3

2-

Procedure: Place 1 microspoon of reagent SO3-1K into the cell, close tightly and shake until the complete dissolution of the solid. Then pipette 7 ml of the sample solution into the cell and mix. After the reaction time of 2 min fill into 50 cells and measure in the photometer at 410 nm. Prepare the blank required for the measurement according to the above-mentioned procedure using 7 ml of distilled water instead of the sample solution. Alternative methods 2)

No. 1.14564.0001 Suspended Solids (physical measurement - application) Turbidity (physical measurement - application) are methods where the turbidity is measured. As the optical system of every spectrophotometer is different, we convince you to determine the factor for your spectrophotometer by your own and program it in your photometer. Non-linear calibration or absorption-concentration- table. 4)

Calibration curves for the methods are non-linear. 1. Use the below mentioned concentration-absorption-table 2. Beside using the concentration-absorption-table you can enter a non-linear curve by using the coefficients of

the following formula. C = a + bx + cx2 + dx3 Check your instrument and enter the coefficients according the given list. The calibration is always done against distilled water.

3. We recommend to take a standard and check if the calibration is done correctly because also spectrophotometers have small differences from instrument to instrument.
