Abstract: This invention discloses a method for constructing a set of database of one or more saccharides, a logical procedure for automatic determination of sequential mass spectra, and a method, program and system for determination the structures of oligosaccharides and glycoconjugates by the set of database. In one aspect, the sequential mass spectra measured by the method, program or system of the invention maybe instructed according to the logical procedure automatically or manually determined. By comparing the sequential mass spectra to the set of database, the structure of the carbohydrate comprising linkage position, anomeric configuration, composed monosaccharide and branch location of the carbohydrate sample can be identified. In another aspect, the method, program may be used to control one or more mass spectrometer automatically or manually.
