Abstract
Based on the m/z of a precursor ion used in an MSanalysis of a test sugar chain, a plurality of sugar-chain structure candidates are extracted from a sugar-chain database in which various sugar-chain structures are related to m/z (S). Product ions that can be generated by cutting one sugar-chain bond are calculated for each sugar-chain structure candidate (S). For each combination of two sugar-chain structure candidates, the product ions of one candidate are compared with those of the other to extract characteristic product ions for each sugar-chain structure candidate, and their m/z values are calculated (S). Whether or not an MSspectrum of the test sugar chain has a peak located at m/z of any of the characteristic product ions is determined, and based on the determination result, the sugar-chain structure candidates are narrowed down (S) and the obtained result is shown on a display unit (S).
