How much is a mass spectrometer?
The prices of different manufacturers will be different. Different models from the same manufacturer are different. There is a difference between gas phase and liquid phase. The cheapest is gas-phase quadrupole mass spectrometry. Cheap ones are all in 400 thousand. QQ (triple quadrupole), IT (ion trap) and TOF (time of flight) are all in the millions. Mass spectrometry used in liquid phase is more expensive than gas phase. Mainly the technical problems of connecting wires.
