Abstract
In positive-ion fast atom bombardment (FAB) mas spectrometry, the abun dance of [M+H](+) ion of mono- and di-saccharides is too low to allow determination of their molecular weights. However, when mono-and di-sa ccharides are mixed with an appropriate amount of NH4Cl, a highly abun dant peak [M+NH4](+) appears in FAB mass spectra. From the adduct ion [M+NH4](+), the molecular weights of mono- and di-saccharides can be d etermined definitively. Here, twelve monosaccharides and six disacchar ides have been studied.
