Abstract
Unimolecular decomposition spectra of oxonium ions from peracetylated pentoses can be used for identification purposes. The fast-atom bombar dment mass spectra of an oligosaccharide with a pentose residue at the non-reducing terminus also contain this oxonium ion, which allows ide ntification of this monosaccharide residue by a tandem mass spectromet ry experiment. The applicability of this method is demonstrated using a xylopentaose.
