In positive-ion fast atom bombardment (FAB) mass spectrometry,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.
