Abstract: Based on the m/z of a precursor ion used in an MS2 analysis 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 (S2). Product ions that can be generated by cutting one sugar-chain bond are calculated for each sugar-chain structure candidate (S3). 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 (S4). Whether or not an MS2 spectrum 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 (S5) and the obtained result is shown on a display unit (S6).
