Discussions about GC and other "gas phase" separation techniques.

Hi. I'm working with an old Varian GC/MS 4000. Since some days it couldn't get ready for analyze samples cause the pressure did't rise. The GC remained, usually, around 2 psi instead of 30 psi. the problem have been solved with a fan in front of the gc without a pannel (directed in the electronic flow system). With the air movment it got the right pression (this as happened for some weeks). During an analysis it stopped working. we tried to bypass the injector, to calibrate the flow and check for lick but the pressure now are set on value zero.
