Refinery GAs Analyzer

Running a refinery  gas analyzer and getting a lot of variance in the response of all the peaks on the FID.  The TCD channel is very reproducible.  The gas is injected by a valve with a 0.1ml sample loop. All the valves are turning properly.  I have leak checked all of the connections and replaced liner, gold seal, septum, and column ferrule and none of that has helped.  Any ideas on what I should try next?  Thanks!
