Welcome to the Mass Spectrometry Terms and Definitions Project Page

This goal of this site is to provide information about and discussion of the IUPAC sponsored project to update the Standard Terms and Definitions for Mass Spectrometry. The site is built around a ' Wiki,' an on-line user editable glossary of mass spectrometry terms and definitions (for an example of a general WIki, see the Wikipedia).

There are currently 2,240 entries in Mass Spec Terms as of Wednesday September 10, 2025.
