Understanding QMS data
« on: April 21, 2021, 05:20:00 PM »
Hi,

I am currently trying to learn about mass spectrometry. I have the opportunity to fiddle with some instruments and one SRS RGA provides a P v T, plot for specific masses. How to I convert the pressure (Torr) to amount (ie ppm), if I dont know what the total pressure of the system is?
