WebHILIC Overview. HILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in nature (> 60-70% solvent, typically acetonitrile) containing a small percentage of aqueous solvent/buffer or other polar solvent. The water in the mobile phase forms an ... WebHILIC separation is based on passing a mostly organic mobile phase over a polar stationary phase. This forms a water enriched layer next to the stationary phase.

WebHILIC SPE can be used for glyco-profiling, i.e., for determining the glycan heterogeneity at one specific glycosylation site, for enrichment of glycopeptides from a complex mixture of peptides, as well as for pre-fractionation of complex samples at the protein or peptide level. In this chapter we present a straightforward HILIC SPE enrichment ... Weba HILIC-UV/FLD method was developed and glycan identification was performed with LC-MS experiments. HILIC, paired with UV or fluorescence detection, provides a robust and unique detection tool for routine analysis (e.g. glycoform stability studies)—with retention times as qualitative and peak area as quantitative information. boa grand nationals 2017 https://matthewdscott.com
