How to convert the concentration of H2 gas 50 PPM to micromoles?

24 October 2024 1 2K Report

Dear Sir/Madam,

Kindly help me with this doubt, I am injecting 50 PPM H2 gas standard for the calibration of 1 mL (1000 micromole). I need to convert this PPM to micromoles kindly help me.

Thank you,

Elena Ehrmann

In the gas phase, mol% is equivalent to volume%. If you need ppm v/v you do not need any conversion. If you need ppm m/vol, you use the molecular weight to convert H2 mol into mass
