Chromatography carrier gas cylinder pressure
Thread Content
I would like to ask the experts: where can I find an authoritative guideline regarding at what pressure level the pressure in a chromatography carrier gas cylinder should be reduced, requiring its replacement? Thank you
In other words, at what pressure below which the gas can no longer be used? Where can one find a relatively authoritative figure for this lower limit?
I don’t know the exact threshold, but at least make sure that the supply of carrier gas to your chromatograph is not insufficient
As long as it is not lower than the carrier gas pressure required for chromatography operation! The most cost-effective way!
