Scrubbing Sulfur species (H2S, SO2, COS) from sample gas
Posted: Fri May 01, 2026 3:06 am
Hi all,
I am analysing a few different components in my gas sample including CO, CO2, N2, CH4 (potentially C2H4, C2H6 and C3H8 in near future). I currently have Carbon plot column installed in an 8860 GC system. But I am thinking to switch my column with Permanent gas select/ CO2 as I also want to measure O2 and H2 in my samples.
The problem I am facing is removal of sulfur species from my sample including H2S, COS, and SO2. The total concentration of the sulfur speacies in my sample is around 0.5 mol%. My current carbot plot can handle the sulfur compounds but since I am thinking to switch to Permanent gas select/ CO2, I am looking to find a solution for removing sulfur species in my sample that won't affect the concentration of the other components in my system.
Any suggestions or experiences with suitable sulfur traps or conditioning methods or any other possible solutions to my problem would be greatly appreciated.
Thanks!!
