Hello,
I got a very basic questions, to explain to a trainee. I recognised that some questions from him i could not answer for sure.
The carrier Gas is to transport the Sample. The last system we used has N2 + H2. One of them has even He.
I saw i pressurised Air Vent leading to the Hydrocarbon Filter and after going to "Detector Air "
I assume that the Gas DONT run over the column. It would not make sense to me.
Thank you in advance for your help.
