Hello all,

I am setting up an IRMS lab and was wonder what experience people have had
using in line filters on their supply and standards gases. In my past
experience with GC/MS systems, even using HP and UHP gases (4.5-5.0) it was
always recommended to have moisture traps on the gases. Has anyone
experienced problems doing this on a EA-IRMS system? Or do you assume that
the gases are ultra-clean from the supplier and leave it at that? An
recommended filters to get or stay away from for IRMS work? Thanks,

Howard
