Abstract

The present invention is a mass spectrometer () for sequentially performing a measurement for a plurality of target ions, characterized by a storage section () for holding ion time-of-flight information concerning the time required for each of target ions to fly through each of the sections constituting the mass spectrometer, and a voltage controller () for changing, based on the ion time-of-flight information, the voltage applied to each of those sections to a voltage suited for each target ion, with a time lag corresponding to the difference in the timing of the arrival of the target ion at the section concerned.
