Hi there. I need your help. My gas sample is including hydrocarbons, CO and CO2, I was told I should used TCD detector, I used but there is no peak. I believe I need to use both FID and TCD detectors at same time and for that I need connector series between TCD and FID, right?
I am trying with Scotty 4 with nitrogen balance , but no results. Is helium better as carrier gas than N2?
Any suggestions would be appreciated.
