Abstract
A plurality of partial mass-to-charge-ratio ranges are defined so that neighboring partial mass-to-charge-ratio ranges overlap each other at a mass-to-charge ratio of a reference ion (Step). Mass spectrometry data of a known compound is acquired in each partial mass-to-charge-ratio range (Stepsand). A normalization coefficient is determined based on a measured intensity of the reference ion in the mass spectrometry data acquired in each of the neighboring partial mass-to-charge-ratio ranges (Stepsand). Mass spectrometry data of a measurement-target sample is acquired in each partial mass-to-charge-ratio range (Step). The mass spectrometry data of the measurement-target sample acquired in each partial mass-to-charge-ratio range is normalized by being multiplied by the corresponding normalization coefficient (Step). The normalized mass spectrometry data of the plurality of partial mass-to-charge-ratio ranges is integrated into one set of mass spectrometry data (Step).
