More Information
Summary:A time-of-flight mass spectrometry device includes an electrode to which a DC high voltage is applied in order to form an ion flight space and a high voltage power supply device that applies the high voltage to the electrode. The high voltage power supply device includes a high voltage generating circuit that generates the high voltage, and a voltage control circuit that is selectively set to a convergence responsiveness priority mode in which the high voltage generating circuit is controlled such that the high voltage has first convergence responsiveness and first stability or a stability priority mode in which the high voltage generating circuit is controlled such that the high voltage has second convergence responsiveness that is lower than the first convergence responsiveness and second stability that is higher than the first stability.
