Journal of the American Society for Mass Spectrometry (JASMS) is a monthly, peer-reviewed journal that covers all aspects of mass spectrometry, including fields of scientific inquiry in which mass spectrometry can play a role. JASMS was launched in 1990 as a bi-monthly publication with Michael L. Gross as Editor in Chief. In 1993, the publication frequency was increased to monthly. As a service to the community, beginning in 1996, the Journal’s archive of online content 12 months old or older was made freely accessible to all.
