Abstract

IUPAC Standard Definitions of Terms Relating to Mass Spectrometry

Keywords: IUPAC, Nomenclature, MS terms, terminology.

The most recent edition of the International Union of Pure and Applied Chemistry (IUPAC) for terms and definitions related to mass spectrometry is over 10 years old1.

A project to update these terms and definitions in keeping with the ever burgeoning field of mass spectrometry has been commissioned by IUPAC and a working party set up to prepare a new document in conjunction with the mass spectrometry journals, national mass spectrometry societies, and the International Mass Spectrometry Society.

A web discussion group2 for MS terms and definition has been created to ensure that wide participation for discussion is achieved to aid production of this comprehensive list and the first workshop was held at this year's ASMS meeting in Nashville.

Here we present a draft report of the project and terms in use and request feedback on these and any other terminology that should be included in the final report to be delivered on 2006
