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