On: Qatar helium shutdown puts chip supply chain on a two-week clock

Do you know if the other 20% is oxygen (as was claimed) or if it's air? I just think the latter seems cheaper and more likely.

I think it may be CO2. CO2 in the gas would cause all sorts of unpleasant effects that would discourage continuing to breath it, and CO2 is probably cheaper to store and transport than oxygen.
