separation of CO2 in Pure O2 (need help)
Posted: Thu Nov 20, 2008 7:23 pm
With a GC with PED
Using Hayesep D 10' mesh 100/120(porous polymer) with a heartcut configuration, why is there a strange round bump during the CO2 integration time.
When I run a cycle with 1ppm CO2 in Helium, there is a nice CO2 peak.
However, when I run pure O2, I got a strange round bump during CO2 integration.
Is someone knows if it comes from the columns or the sample gas???
