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; and a control unit that controls outputs of the ion drive circuitry and the field drive circuitry, wherein the control unit controls the ion drive circuitry to ramp up and down a filament voltage supplied to a filament of the ionization unit when the analyzer apparatus starts and stops.
