I'm no expert, but I don't think a mass spectrometer actually requires a
particularly powerful magnet. (It's only throwing microscopic particles
around, after all.) The photomultiplier might be expensive; I don't know
how it works. The ADC is probably quite expensive as chips go (although
not hundreds of thousands of pounds, I wouldn't have thought).
