The Mudlogging 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 exact composition of the sample stream.
The sample gas stream (at a regulated pressure) is connected to the bulkhead fitting on the GC's heated valve oven where it flows through the loop of the 10-port gas sampling valve, and also to the second FID detector, which continually monitors the total hydrocarbon content of the gas. Automatically, at a repeating time interval controlled by the operator, the gas sampling valve injects the contents of its loop into the GC column, where it is separated into the constituent hydrocarbon peaks and detected by the first FID detector.
The built-in, six channel PeakSimple data system displays both the continuous total hydrocarbon reading and the separated peaks. An alarm function alerts the operator for any out-of-range readings. Summary reports are easily printed to Excel or similar programs.
The top chromatogram is the FID speciation of C1-C4 hydrocarbons in less than four minutes, with backflush of C5 and higher compounds. In the bottom chromatogram window, PeakSimple's Data logger mode displays the continous total hydrocarbon reading.
