MIP Channel Overview
ZEBRA
The probe is advanced 1 foot + wait 1 minute (Gas Trip Time). Note that the detector output line consists
of a number of spikes that represent advancement of the probe and related changes of contaminanttransfer across the membrane. Additionally, light (and more volatile) compounds (such as benzene in caseof gasoline plume) within the contaminant mixture go across the membrane faster that heavier compounds,creating a leading spike. The scale uses exponential format (also called (scientific notation) to representoutput values. 5E+6 means 5 x 10^6 (five times ten to the power of six), so it is 5,000,000 (microvolts). The scale is set to auto-scale by default, modifying the graph to fit the scale as detector responsevalues go up. All detector units are micro Volts (uV) - represents voltage output from electrometer,correlating with contaminants concentration (remember, this channel does not show actual concentration,only detector output; you need to know the response factor and dilution factor to figure that out; sothe easiest way to do it is to grab a representative sample and establish a correlation for a given siteand given contaminant).
Channel Information:
1. Conductivity:Units of measure are milliSiemens per Meter (ms/M); (remember, actual values are representative within agiven geologic formation: silt in Florida may have different electric conductivity than silt in Massachusetts).
2. Speed:[Speed of probe penetration]. Future use.
3. PIDThe PID, Used when delineating a Petroleum Hydrocarbon or Chlorinated site.
4. ECDUsed when delineating chlorinated site. The ECD detector generally is very stable except when entering thewater table. Increased water vapor concentration causes the ECD's baseline to drop at the groundwaterinterface. Additionally, the ECD's baseline has a tendency to slope down as the probe is advanced deeper(noticeable when going below 50-60' BLS), as the amount of water going across the membrane increaseswith increasing pressure. The same is true for the PID detector, to a smaller extent. Since an in-line dryerwas installed on the ZEBRA's MIP units, the water vapor effects become less expressed, with PID remaininglargely unaffected by changes in water vapor concentration
5. FIDThe FID can detect light hydrocarbons, such as methane or butane, which are out of reach for the PID. Youcan have a really high response on Detector 2 channel with nothing on Detector 1. In such case the chancesare that youve run into an area with anaerobic degradation processes present, or you have detected apresence of light gaseous hydrocarbons from some other source. The FID is not affected by water vaporconcentration, so generally it's response is not affected by entering the groundwater table.
6. Temperature:Shows output of a thermocouple built into the MIP probe's heating plate. It is useful for monitoring systemperformance and for troubleshooting. Each time the probe is advanced to the next depth increment, thetemperature graph goes down; as soon as the probe stopped, the temperature starts to go back up untilfurther heating is inhibited by the heat absorption capacity of the formation (on the surface, the relay isset to shut off the heater once it reaches the temperature of 120 C). As per ZEBRA's Standard OperatingProcedures, the temperature should be allowed to reach 80 C (in the Low Sensitivity Mode), or to exceedthe Boiling Point of the target compound (in the High Sensitivity Mode). The temperature channel is a highlyuseful quality control tool, as it is possible to check MIP operator's adherence to an established loggingprotocol on each and every log:

Understanding the processes that take place at the Membrane Interface is important for providing accurate
interpretation of the MIP logging data.
The carrier gas pressure is maintained at 4 to 8 psi on the
inner side of the membrane. This prevents the water from
breaking through the membrane by maintaining a pressure
gradient across the membrane. The presence of the gradient,
however, is not interfering with the transfer of the VOC
molecules across the membrane in a direction opposite to
the pressure gradient. The reason is the mechanism of the
VOC transfer: the VOC molecules are NOT transported by
the flow of the gas diffusing through the membrane pores
(since that flow is actually towards the outside of the probe);instead, they get absorbed into the hydrophobic matrix of
the membrane (Teflon TFE) and get desorbed on the other
side of the membrane, where they get picked up by the car-
rier gas flow. The movement of the molecules results from
a concentration gradient instead of pressure gradient, much
like in osmosis.
The heating of the membrane increases the rate of the trans-
fer, increases vapor pressure for VOCs present in the soil
adjacent to the membrane, and volatilizes some of the com-
pounds with low vapor pressures at the ambient tempera-tures.
Based on our experience, semi-volatile compounds are also
transferred across the membrane; however, they usually pre-
cipitate in the tubing above the membrane as the carrier gas
cools down. The presence of heavier compounds inside of
the tubing as a result of precipitation can create secondary
hits when a lighter solvent is introduced, (thus the impor-
tance of a proper QA/QC and purging).
