Abstract
Maltotriosyl- and panosyl-alpha-cyclodextrins and the nonaose of pullu lan were analyzed by post-source decay (PSD) fragment methods of matri x-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectroscopy, By the mass number analysis, it was found that all of t he PSD fragment ions were produced by cleavages of glycosidic linkages . Comparison of the relative intensities of the ions in those compound s enabled us to distinguish two kinds of glycosidic linkages, alpha 1- 4 and alpha 1-6, by MALDI-TOFMS with a new type of ion reflector: the curved field reflectron.
