Abstract: An analyzer apparatus includes: an ionization unit that ionizes molecules to analyze; a filter unit that forms a field for selectively passing ions generated by the ionization unit; a detector unit that detects ions that have passed through the filter unit; an ion drive circuitry that electrically drives the ionization unit; a field drive circuitry that electrically drives the filter unit; a control unit that controls outputs of the ion drive circuitry and the field drive circuitry; a temperature detecting unit that detects the temperature of the ion drive circuitry and the field drive circuitry; and a correction unit that corrects output settings of the ion drive circuitry and the field drive circuitry based on the temperature detected by the temperature detecting unit.
