Abstract
Provided is a packing material for HILIC columns for more accurately and more easily performing oligosaccharide analysis by liquid chromatography; an HILIC column which is filled with the packing material for HILIC columns; and a method for analyzing an oligosaccharide with use of this packing material for HILIC columns A packing material for HILIC columns according to the present invention is composed of particles, each of which is obtained by reacting glycidol to a hydroxyl group of a porous cross-linked polymer base material having the hydroxyl group, and which have a hydrophilicity index of 2.30 or more and a surface-pH index of from 0.95 to 1.05.
