Standard Definitions of Terms Relating to Mass
This document contains recommendations for nomenclature,
definitions of terms, and acronyms in mass spectrometry. In 1974, the
IUPAC Commission on Analytical Nomenclature issued recommendations on
mass spectrometry terms and definitions. In 1978, the Commission on
Molecular Structure and Spectroscopy updated and extended the recommendations
and made further recommendations regarding symbols, acronyms and abbreviations.
The Physical Chemistry Division Commission on Molecular Structure and
Spectroscopy's Subcommittee on Mass Spectroscopy revised the recommended
terms in 1991 and appended terms relating to vacuum technology. Some
additional terms related to tandem mass spectrometry were added in 1993
and accelerator mass spectrometry in 1994. Due to the rapid expansion
of the field, particularly in mass spectrometry of biomolecules, a further
revision of the recommendations has become necessary.
