1. A mass spectrometry device which performs a channel scan measurement by changing a voltage to be applied to a mass separation unit to selectively extract a desired ion, the device comprising:

  • an ion detection unit which detects an ion separated by the mass separation unit and outputs an electric signal;

    an ion amount measuring unit which measures an ion amount from the output of the ion detection unit; and

    anion amount correction unit which corrects a detection amount of ion from an output of the ion amount measuring unit, whereinin a process of a channel scan, the ion amount correction unit performs correction of a detection amount of ion detected in a present channel based on a detection amount of ion in a previous channel.
