I'm new here, and to GC in general.
I would like to measure the contaminants in rather pure hydrogen (higher than 99,5 % I would guess). Mainly CO, CO2, CH4, N2 and higher hydrocarbons (C6, C7), the hydrogen also contains traces of water, according to the FTIR analysis.
I wonder if a Shin Carbon ST column + HID is the way to go (see http://www.restek.com/pdfs/PCTS1472-UNV.pdf Fig. 1). Maybe it needs some kind of pre-column to prevent higher hydrocarbons from entering the Shin Carbon column (another short Shin Carbon?) and an FID, to quantify those.
I would love to hear your opinions, as I'm quite a newbe to GC.
Cheers
