# How does mass spectrometry differ from other forms of spectroscopy?

There are much better Mass Spec ionization chamber variations, like CI and ESI, and there are other kinds of Mass Specs that ARE nondestructive, like Fourier Transform Ion Cyclotron Resonance (FTICR), Time-of-Flight (TOF) spectrometers, and Orbitraps, but they are on the more expensive end of mass analysis instrumentation out there (on the order of $800000~$2000000 for FTICR spectrometers).
