Abstract
Nonuse-indication information can be set for each peak on a mass spectrum collected in a compound database, as attribute information, the nonuse-indication information allowing the selection of whether to be used in a database search. For example, nonuse-indication information is set in advance to a noise peak mixed in actual measurement, an impurity-originated peak, and the like. In identifying a compound, when nonuse-indication information is read from the database for a database search together with a mass spectrum, an unnecessary information deleting section transmits a mass spectrum from which a peak set with the nonuse-indication information is deleted, to a compound candidate extracting section and a scoring section. Therefore, a peak set with the nonuse-indication information is ignored in, for example, calculating the score of a compound candidate, which allows a score with a high accuracy to be calculated, resulting in an improved identification accuracy.
