Journal of the American Society for Mass Spectrometry

Aims & Scope

The Journal of the American Society for Mass Spectrometry is devoted mainly to the publication of research papers covering all aspects of mass spectrometry.

Papers from all fields of scientific inquiry in which mass spectrometry can play a role will be considered.

These fields include chemistry, physics, geology, and environmental science as well as the biological, health, and life sciences.

Contributions must not have been published elsewhere.

The journal is intended to be comprehensive, and its aim is to publish papers on both fundamentals and applications of mass spectrometry.

Fundamental subjects include, but are not restricted to, instrumentation principles, design, and demonstration, structures and chemical properties of gas-phase ions, studies of thermodynamic properties, ion spectroscopy, chemical kinetics, mechanisms of ionization, theory of ion fragmentation, cluster ions, potential energy surfaces, and modeling.
