Hi,
We have an Agilent MicroGC working for pyrolysis of bilmişsin. We use Helium to purge air and create an Oxygène free atmosphere in our reactor that is online with GC. During the last several analysis, when we start with Helium, Oxygene appears around 3 mol gram in raw analyses. Without Helium, no problem for air (blank) composition or no problem in standard gas analyses for calibration. Problem is Oxygene leak appears with Helium. We changed today the tube but... do you have any idea? Thanks before
