Abstract Positive‐ion fast atom bombardment mass spectrometry appears to be a useful method for the differentiation of anomeric C ‐glycosides. The mass‐analysed ion kinetic energy (MIKE) and collision‐activated dissociation (CAD) MIKE spectra of selected positive ions can be used as fingerprints of the α‐ or β‐anomers. The main fragmentation routes and particularly the formation of the [M − H] + ion and the [M + H − PhCH 2 OH] + ion were traced for each anomer.
