Application of matrix-assisted laser desorption/ionization (MALDI) to the analysis of dextran and dextrin derivatives, specifically glucose saccharides, by time-of-flight (TOF) mass spectrometry is reported. MALDI-TOF analysis was carried out on alpha-, beta-and gamma-cyclodextrin, two O-methylated beta-cyclodextrins of differing degrees of substitution (DS) and dextrans (a linear glucose saccharide), as pure and doped solutions and as mixtures of two or more of these analytes. Doping was carried out with trace amounts of inorganic salts. The purpose of the analysis of the cyclodextrins was to determine whether they would form inclusion complexes with the various added cations, or whether less specific cation addition/exchange was occurring either prior to desorption or in the gas phase.
