Isomeric oligosaccharides analyses using negative-ion electrospray ionization ion mobility spectrometry combined with collision-induced dissociation MS/MS.


Ion mobility-mass spectrometry (IM-MS) was applied to analyses of isomeric oligosaccharides linked by alpha1-4, alpha1-6, beta1-3, and beta1-4 glycosyl linkages. Negative-ion electrospray ionization (ESI) quadrupole IM time-of-flight mass spectrometry allowed the combination of IM separation and collision-induced dissociation (CID) MS/MS product ion… (More)
