Hi Ausama, please see the link, https://www.researchgate.net/post/How_do_I_calculate_the_gas_concentration_in_PPM

Md Tawabur Rahman

The following equation might be helpful.

ppm=(volume of gas/volume of chamber)*concentration (ppm) in cylinder

Sajjad Hajian

Hi Ausama,

For calculations, if you are using 1 gas molecule in a specific area, if you can find the volume of the gas molecule, you can use the following:

ppm = (volume of the molecule)/(volume of the area)
