title: Gas-phase fragmentation of oligosaccharides in MALDI laser-enhanced in-source decay induced by thermal hydrogen radicals.
abstract: Laser-enhanced in-source decay (LEISD) MALDI MS recently proposed for structural analysis of oligosaccharides was used to systematically investigate ISD fragmentation of oligosaccharides, which was found to be mediated by thermal hydrogen radicals from a matrix and underwent a charge-induced process, depending on the nature of the matrix and the structure of an oligosaccharide.
