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
and also to the second
, 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,
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.
