Abstract
A precursor ion selection processing unit () sequentially selects precursor ions having different mass-to-charge ratios, and causes an MS/MS spectrum data acquisition processing unit () to acquire MS/MS spectrum data corresponding to each precursor ion. The precursor ion selection processing unit () sequentially selects the precursor ion having a mass-to-charge ratio which is not included in a predetermined range with respect to a mass-to-charge ratio of the precursor ion for which the MS/MS spectrum data has already been acquired.
