Reaction mechanism and fragment ion structure determination of deprotonated small oligosaccharides, studied by negative ion fast atom bombardment (tandem) mass spectrometry.


The negative ion mass spectrometric characteristics of a series of di- and trisaccharides and the tetrasaccharide stachyose have been studied using fast atom bombardment mass spectrometry. The molecular weight of the compounds can easily be derived from their mass spectra, which all show an abundant [M - H]- ion peak. The application of metastable ion and… (More)
