Greetings,

I'm using GC-C-IRMS and I'm having a problem with my reference CO2.  The
reference gas is plumbed directly into the GC oven, flows through the
combustion furnace and nafion water scrubber, and finally to the mass
spec.

It seems that as my GC oven temperature increases, my reference gas peak
sizes decrease.  Has anyone witnessed this on their system?  Any
suggestions?

Cheers,

Brian
