The PSD spectra of some isomeric oligosaccharides are investigated in order to study the fragmentation mechanisms. Results show that intense peaks are formed from one or more glycosidic linkage cleavages, while ring fragmentation produces very weak signals. Two analytical applications of post source
## Abstract We have acquired multiโstage mass spectra (MS^__n__^) of four branched __N__โglycans derived from human serum IgG by matrixโassisted laser desorption/ionization quadrupole ion trap timeโofโflight mass spectrometry (MALDIโQITโTOFโMS) in order to demonstrate high sensitivity structural an
