Abstract
A TOFMS includes flight space formation electrodes, an ion detection unit, voltage switching units to switch a voltage to be applied to the flight space formation electrode from a first voltage for flying ions of a first polarity to a second voltage for flying ions of a second polarity, ion information acquisition units to obtain a time of flight or a m/z of the ions based on a detection result of the ions of the second polarity after the voltage has been switched, a correction information storage unit to store correction information related to a deviation in time of flight or a m/z associated with an elapsed time from the switching timing, and a correction unit to correct the flight time or the m/z according to an elapsed time from the switching timing when the detection result of the ion is obtained using the correction information.
