We are required to order all our gases through Campus General Stores.  They use Airgas for all gases, but the Airgas rep works with other vendors when they can't meet the request.  I have both a 6% and 9% PH3 in Silane on-site in 7liter cylinders with DISS (CGA 632) fittings and pneumatic valve.  They were provided by AirLiquide (who acquired Airgas).

Good morning all,

Who have you used to supply the custom gas mixes for your fab, particularly the HPM products?  We have an application where we want to procure some 15%PH3 in Silane, and the current provider has fallen on their face repeatedly in over-promising, and under-performing.  We're typically looking at smaller cylinder sizes (4-6" diameter, and 16-24" tall), with DISS cylinder valves.

I have to believe this is a niche market, but someone must be doing it....

Thank you,
