Dear colleagues,

I was just asked by someone who is setting up a lab how feasible it is to 
run mostly SO2 analysis on an isotope ratio mass spec, but also some O and 
D in water and N and C in organic material from a EA.  I don't do S 
analysis, but in the past my understand was that it was desirable to have a 
separate mass spectrometer for SO2 analysis if possible.  My understanding 
was that SO2 would gradually affect the source and the results for O in 
particular but possibly other more stable compounds would deteriorate 
compared to a system that does not run SO2.  However, with modern 
continuous flow systems perhaps this is not as great an issue.

Any advice on this would be appreciated.

Paul Brooks.
