✦ Synopsis

Fast atom bombardment mass spectrometry of alkali metal cationized unsaturated C-glycosides is a useful method for the determination of the molecular masses of tbese compounds. The mass-analyzed ion kinetic energy and collision-activated dissociation mass-analyzed ion kinetic energy spectra of the pairs of anomers are distinguishable and are characteristic of each anomer.
