Query for GC analysis of Biogas using Argon carrier gas

[mail2chandru]

We are using Porapak Q column (mesh: 80/100; L - 2m; 1/8" diameter) for detection of biogas analysis using Argon as carrier gas (30 mL/min; 40 deg.C (oven); injector - 125 deg.C; detector - 100 deg. C). We have problem in detecting H2 peak which coincide with Air (N2, O2). Kindly suggest and provide any model plot for the same. I would appreciate the concern.

[/color You can try Shincarbon column from Restek.

Or a molecular sieve, but you won't see a CO2 peak
