Mass spectrometry doesn't use electromagnetic radiation, hence why it is not called Mass spectroscopy. Instead Mass spectrometry uses high energy electrons to ionize the sample molecules, which helps determine the mass of the molecules and any fragmented ions from the parent ion.

IONICS Mass Spectrometry Group's motto is 'IONICS Mass Spectrometry Group: Company'.

Mass spectrometry provides more structural information about the molecule.

Journal of Mass Spectrometry was created in 1995.
