I am ordering some calibration gases to develop a method for my gas cell equipped FTIR. The gas cell is roughly 2 liters in volume and I vacuum it down to -28 in Hg. I want to run the samples at 20 psig. I have another cylinder from the company I am going to order from that says it is 34 L when...
So I am trying to determine the volume of a gas that has been put through a filter so I can do some calculations.
I randomly have the formula Density (lb/Ft3)* Volume (Ft3/min) = 2.5985
But I am not sure where I got this from. The only things I know are what type of gas it is, the PSI that gas...
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...
