Laser desorption mass spectra of malto‐oligomers, including starch, have been obtained using Fourier transform mass spectrometry. Fragmentations of these oligomers have been examined after doping with metal salts to obtain cation‐attachment ions. Doping starch with NaCl, KBr and Ag 2 O results in analogous cation‐attachment oligosaccharide fragment ions for all three metal ions. A distinct and unusual fragmentation pattern is observed for the larger oligomers.
