If analyzing sugars with HILIC chromatography, the sugars can form anomers (open chain vs. closed chain). 6. The column might be dirty (buildup of sample matrix). If only some peaks are split within a mixture of several other peaks: 1. Strong sample solvent effect (sometimes affects early eluting peaks); for example:
WebJan 1, 2024 · HILIC is another frequently used analytical tool in the field of HMO analysis. HILIC was originally developed to analyze polar and ionic species. In case of sugar analysis, 2-AB is the most frequently used labeling reagent. The method is well suited for the separation of longer positional and linkage isomers, including sialic acid isoforms [28].
