WebFor all three glycan pairs, a more negative CoV was observed for the α2,3 isomer than for the α2,6 isomer, suggesting that the α2,3 isomers bind more strongly with the methanol vapor than the α2,6 isomers11-13. Conclusions In this study, differential mobility spectrometry (DMS) was used to analyze pairs of mono- and di-sialylated glycan ... Webpairs of isomers. Figure 4. G1F glycan isomers and anomers are separated on the PGC column. MS/MS spectra were collected. Anomers have similar MS/MS fragmentation pattern using same collision energy, while the isomers exhibits very different MS/MS pattern. Figure 5. This example illustrated the fragmentation pattern from sialylated glycan.
