Abstract
A mass spectrometer includes an ion source that generates ions, an ion trap that captures the ions generated from the ion source, a detector that detects the ions ejected from the ion trap and a controller that controls a periodic voltage, which is added to form a capturing electric field in the ion trap and controls a time point at which the ions are generated from the ion source. The controller includes an ion generation time controller that allows the ions to be generated from the ion source at N (N is an integer equal to or larger than 2) phase time points while addition of the periodic voltage is continued, the N phase time points being set in one period of the periodic voltage and being respectively assigned to different periods of the periodic voltage.
