Hot Cathode Ion Gauge Mass Spec?

I was looking at Rapp ents' interestingly simple pipe tee mass spectrometer, and it occurred to me that one could possibly use a Hot Cathode Ion gauge controller as the essential electronics to a simple mass spectrometer. These instruments are dirt cheap if you don't care about cabling, so I'm interested to hear if anybody has any comments on this Wacky Scheme.
