摘要：

In positive-ion fast atom bombardment(FAB) mass spectrometry, it is difficult to determine the molecular weights of oligosaccharides due to the low abundance of [M+H](+) ion, However, when oligosaccharides are mixed with an appropriate amount of NaCl and LiCl, two highly abundant peaks [M+Li](+) and [M+Na](+) appear in FAB mass spectra and their mass difference is 16. From the adduct ions, the molecular weights of oligosaccharides can be determined definitively, This technique has not been reported previously.
