Abstract
A method for preparing an analytical sample for analysis of a glycan contained in a sample includes: performing an amidation reaction that amidates a lactone structure included in the glycan through contacting the sample with a reaction solution that is basic; adding an acidic solution to the reaction solution after the reaction solution is subjected to the amidation reaction; and purifying the sample contained in the reaction solution after the acidic solution is added to the reaction solution by using a carrier for hydrophilic interaction chromatography.
