摘要：
The potential of travelling wave ion mobility spectroscopy in combination with collision induced dissociation tandem mass spectrometry (CID-TWIMS-MS/MS) to separate cereal-derived isomeric arabinoxylanoligosaccharides (A)XOS was investigated. Three trisaccharide, four tetrasaccharide, and four pentasaccharide (A)XOS isomers were analyzed by positive and negative ionization TWIMS-MS and CID-TWIMS-MS/MS. The triand pentasaccharide isomers were distinguishable by the ATDs of the precursor ions. The CID-TWIMS-MS/MS could separate most of the isomeric fragment ions produced from tetra- and pentasaccharide (A)XOS. Finally, the base peak mobility spectrum is introduced as a practical tool for (A)XOS fingerprinting.
