We are running an Agilent 7890A with a Teledyne Tekmar Stratum PTC, Aquatek 70 Autosampler and cryofocusing module. The He gas is routed from the GC inlet to the PTC, through the trap and back into the GC. Am I correct in thinking that the inlet should be operated in splitless mode, because so far it has been running at split 1:10, meaning most of the He doesn't even get to PTC. Or is this done on purpose to minimize pressure surges?
Teledyne seem to have removed most references to that model on their website, does anyone have a digital copy of the manual?
Thanks.
