[TheForge] Argon-CO2 mix question

[Bruce Freeman]

If the argon and CO2 exist as gases in the cylinder,
then separation is impossible.

However, CO2 may exist at that temperature and
pressure as a liquid, in which case separation is
possible.

I would guess that in formulating the Argon-CO2
mixture, this possibility was accounted for, and
somehow rendered irrelevant.  

However, to be sure, you'd have to talk to a technical
man at the gas supplier.  I don't mean the local
welding supply store, but someone back at the
headquarters of the company - like AirGas, MG, etc. -
that does the gas blending.
