A retention index is calculated based on a detection time (more specifically, retention time) of a compound. A molecular weight range and a number-of-carbon-atoms range are specified based on the retention index. A search range is determined by the molecular weight range. A molecular peak searcher searches for a molecular peak in the search range which is set on a mass spectrum of the compound. A composition estimator estimates a composition of the compound based on an accurate mass specified from the molecular peak. In this process, the number-of-carbon-atoms range is taken into consideration.
