Mass Spectrometry of Oligosaccharides(I)—Formation of the [M+Nh4]+Ion of Oligosaccharides in Fast Atom Bombardment Mass Spectrometry

Open publisher page 1 citations

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.
