Abstract

A synchronization condition setting processing unit receives a user's selection regarding an MRM transition for which the timing of starting voltage application to a probe is to be synchronized with the timing of starting analysis. A mass spectrometry control unit controls a mass spectrometric unit to repeat a cycle of executing MRM measurement of a plurality of preset MRM transitions, while an ionization control unit controls a PESI ion source to alternately repeat an up-and-down movement of the probe and high voltage application to the probe, and at that time, a synchronization control unit controls control operations of a mass spectrometry control unit and an ionization control unit such that timings of start of the MRM measurement for the MRM transition selected by the user and start of application of voltage to the probe match.
