Carboxen 1000 for vapor analysis.

[michedido]

Hi,

I'm using a Carboxen column for the analysis of H2, CO, CO2, CH4, O2 and N2 (with argon as a carrier gas).
But I have a problem. I am suspecting that my gas sample (that comes from a gasification reaction with water vapor) is contaminated with water.
The hydrogen peak of my sample is a little bit dislocated, and I wonder if it might be water and not hydrogen.
I am using a temperature ramp - 35oC for 5 min + 20oC/min to 210 oC).

Help!

Water will elute with CO2 on a C-1000 column. But if the pores are dirty or there are heavy components present in the sample, the RT of hydrogen might be affected.

best wishes,

Rod
