I'm hoping someone in the know will chime in.
    I did some more Googling as well, and you guys are likely correct (or I'm likely incorrect ) and the impurity isn't nitrogen.

    Last time I checked Lawrence Factor used FTIR so they wouldn't be able to pick out argon or nitrogen.

    Hello Moose-Grunt,

    My laboratories (family company) will run an analysis (GC) of your gas if you send us in your sample. It's not going to be particularly cheap to get it here as we're based in South Wales, UK. However, we'd be happy to help.

    PM me if you're interested.

    I hope I am not in breach of any forum rules here. If I all of a sudden start getting business from people wanting to analyse their gas in my labs, I will become a sponsor in a flash!

    Chris
