I am trying to analyze a mixture of gases including H2, CO2, CH4, CO, and H2O using a GC 7890A TCD. I read that it is possible to use parallel columns and switch between these columns to analyze H2, CH4, and CO in the first column (Molsieve 5A), then CO2 on the second (I'm planning to use CarboPLOT on this one, but I am also unsure if it could work with moisture?). However, I am unaware on how to install the columns and if my GC has the required valves installed. The GC in my lab has been here for about 5 years now but no one seems to have used it fully.
Is there any way for me to confirm if our GC has these valves, and if it is possible to install 2 columns on our GC?
(Sorry if my question sounds stupid, just completely clueless here )
