Fast atom bombardment mass spectrometry in combination with collisional activation has been used to investigate a number os amino‐ and phosphate‐substituted glucoses and of phosphate‐ and sulphate‐substituted glucosamines. The collisional activation spectra of the [M – H] − ions readily reveal the presence of sulphate or phosphate substituents, whereas specific fragmentation reactions can be used to distinguish among the various positional isomers. The fragmentation of the pseudomolecular cations depends on the number of Na atoms incorporated. By selecting the appropriate pseudomolecular ion it is possible to get information on the nature and/or position of the substituents.
