[en] The differences among MALDI-ISD spectra of hexasaccharides cationized with various alkali metals are reflected in the different stabilities of the ‘hydrogen-deficient’ glycan radical. The stability order of alkali metal-glycan radical complexes is proportional to the size of the alkali metal cation, K+ > Na+ > Li+. The Coordination of alkali metal ions to model branched hexasaccharides is the major parameter that dictates the fragment yield in MALDI in-source decay with hydrogen abstraction using 5-nitrosalicylic acid as the matrix
