Need help calculating PPM (% Mol) in Gas samples

Need help calculating PPM (% Mol) in Gas samples

(OP)
Hello all,

I am using an FTIR to attempt to calculate concentrations of impurities in air and oxygen. I have a standard that I know has 500.5 ppm (% mol) of CO2 and am trying to use the spectrum that I obtained from this sample to back calculate and find this value. Does anyone have any experience doing something like this?

RE: Need help calculating PPM (% Mol) in Gas samples

You also need to know the cell thickness to do that calculation. If you have that, then you can use Beer's law to estimate the concentration.
