摘要： The invention intends to determine a presence ratio between mixed compounds which are difficult to separate from each other by a separation unit and cannot be discriminated by MS. In a mass spectrometer with an MSn analysis function for ionizing a sample eluted from a separation unit for separating the sample into individual components, fragmenting an ion of a desired mass number, and performing a mass analysis of fragment ions, the mass spectrometer includes a database storing correlation information between an isomer presence ratio and a particular ion intensity ratio in a mass spectrum per isomer. An isomer ratio can be clarified even for a mixed sample of isomers, such as enantiomers, which are difficult to separate from each other by the separation unit and cannot be discriminated by MS.

摘要： In a database MSn spectrum search, search of a known compound whose principal chain is identical to that of an unknown compound is enabled, thereby allowing analysis of an entire structure even if the entire structures of the known compound in database and that of the measured unknown compound are not identical. The MSn spectrum obtained in the MSn measurement of the unknown compound is compared with all the MSm spectra (m≧1) in the database regardless of MSn generation. In the MSn measurement of a series of related compounds including various types of different side chains of the same principal chain, such as in the case of biopolymers, it becomes possible to determine the structure of the principal chain using a database search even if the entire structure is not clear. And the estimation of the entire structure is made possible on the basis of the principal chain structure.
