✦ Synopsis

Abstract

Tandem mass spectra of ammonium adducts of monosaccharides gave characteristic fragmentation patterns involving elimination of NH~3~/H~2~O followed by multiple eliminations of H~2~O and cross ring cleavages. Tandem mass spectra were examined over a range of collision energies (1–20 eV) on a triple‐quadrupole mass spectrometer. The breakdown behavior of the ammonium adducts revealed patterns that could differentiate diastereomers of monosaccharides. Copyright © 2006 John Wiley & Sons, Ltd.
