Where can I find the standard/recommended back cylinder pressures for Helium, Oxygen, and Hydrogen (in bar). I work with ICP-MS instruments models 7900, 8800, and 8900.
Find maintenance, best practice, and troubleshooting articles.

Hi, I think you are asking for the input pressure of the cell gases.
you will find them at the back of the instrument.
just divide the kPa values by 100 to get bar.

Dear Chris,
Following the example picture you provided, does this mean that the working pressure (i.e. the outlet delivery pressure of the gas) should be 0.9-1.3 bar (90-130 kPa) for the He cylinder, and 0.2-0.6 bar (20-60 kPa) for H2 and 3rd cell gas cylinders?
Thank you again for your help!
Best,
Francesco
