The Mud-Logging GC system is designed to provide a continuous reading of total hydrocarbons in a gas stream while periodically performing a chromatographic separation of the sample to determine the composition of the sample gas stream. This is accomplished using a 10 port Gas Sampling Valve with a 25?L Sample Loop in a thermostatted Valve Oven a 1m (3’) Hayesep D packed column in a temperature programmable Column Oven a CCD detector an FID detector and a built-in Air Compressor. This GC can be modified to incorporate a second FID instead of the CCD for total hydrocarbon monitoring. The model shown below has CCD and FID detectors.



Speciation of C1-C6 hydrocarbons is handled by the Gas Sampling Valve Hayesep-D column and FID while the CCD provides contiuous total hydrocarbon monitoring. Detection limits for this system are 0.1% to 100% for the continuous total hydrocarbon monitor and 0.005% to 100% for speciated hydrocarbons using the FID. The Air Compressor supplies combustion air for the FID and the air make-up for the CCD. The built-in PeakSimple data system displays both the continuous total hydrocarbon reading using the Data Logger mode and the separated peaks. When the system receives out-of-range readings an alarm function may alert the user.
