What do you mean by chlorinated gas? Chlorinated VOCs such as
chloroform, trichloro-ethylene etc?
 
Such compounds by themselves should not damage any GC column but they
will certainly react with (or inside) your TC/EA reactor should you
inject them into the system. Given the high temperature and reducing
conditions, I could only guess what kind of products will emerge (Paul?;
anybody?) but Cl2 and HCl (possibly even Cl atoms) will be amongst them,
and they will damage your column. That said, I would be equally worried
about the damage halogenated compounds will cause in the TC/EA, if not
more so.

Hi isogeochemists,
I've a question:
can chlorinated gas damage the GC column in the TC/EA mass spectrometer?
Why?
Bye.
