| Abstract: | In positive-ion fast atom bombardment (FAB) mass spectrometry, when oligosaccharides are mixed with an appropriate amount of NH4Cl, a highly abundant M+NH4]+ peak appears in FAB mass spectra. From the adduct ion M+NH4]+, the molecular weights of oligosaccharides can be determined definitively. This technique may especially be applied to analyze the mixture of oligosaccharides. |
