Abstract

Low-energy negative ion mass spectra of glucose and fructose suggest the deep fragmentation of short-lived molecular ions. An analysis of metastable ions in the mass spectra shows that some decomposition reactions proceed through intermediate [M–H2O], etc. ions. Along with the general similarity of the ionization processes in the isomers, there is a significant difference, which is in the intensive formation of m/z 71 ions from glucose.

Keywords:
