Abstract
In a mass spectrometer including ion optical elements for transporting ions or controlling their behavior by electric fields, a device state determiner () determines whether or not the mass spectrometer is in a normal state based on an ion intensity signal acquired by analyzing a predetermined sample. If the mass spectrometer is in an abnormal state, a charge-up determiner () determines whether or not charge-up is present in the ion optical elements based on a change in ion intensity signal in an analysis on the predetermined sample observed when the voltages applied to the ion optical elements are changed according to a predetermined sequence. If charge-up is present, the charge-up determiner determines which ion optical element is likely to have the charge-up. A notifier () notifies a user of the results of the determination by the device state determiner and the charge-up determiner.
