Quadrupole mass spectrometer for measuring H2O and H2S

[prasad31]

I have a quadrupole mass spectrometer with the capillary inlet. I want to use this mass spec for measuring mixture containing H2, CO, CO2, N2, O2, H2O and H2S with H2S in 1-10ppm and H2O in 30-40%. Can i use the quadrupole mass spectrometer with the capillary inlet that i have to measure all these components? will there be any problems i may face? or precautions i need to take? Please answer. Will provide more info if needed any. Awaiting answer ASAP.

inadequate info.........
You have provided no info re your separartion capabilities nor your MS
your manual what mass range can you look at ? Do you have a GC/MS or a Gas quadrupole MS ?

Hi,

from my manual, I can go upto 200 AMU. It is just gas quadrupole mass spectrometer(qms), no GC-MS. I am new in using qms, so i need to provide info from manual. Please ask further info required so that i can provide from the manual. Thanks

In short no. You will need a GC (which I suspect you do have) in order to sepparate the gases with a column. For the gases you are concerned with you would have to scan from 50 to 10.
