摘要： A mass spectrometer that performs ion-molecule reaction ionization and accurately performs qualitative/quantitative analysis on a sample containing multi-components for a short time is achieved without an increase in the size of the device. A plurality of ion sources (3-1 to 3-4) are connected to each other in series. A controller/analyzer (6) controls supply of a voltage from a high voltage source (7) through a discharge needle (8) to any one or more of the ion sources (3-1 to 3-4). When the plurality of ion sources (3-1 to 3-4) operates, normal APCI is performed by an ion source that is close to a sample loading unit (1), and generated ions are discharged to the outside of the ion source by a discharge electrode (9). A residual neutral molecule that is not ionized is transferred by an extraction electrode (10) to an ion source located on the side of a mass spectrometer. Even when it is difficult for an ion source located at a single stage to detect a component, the component can be detected by a combination of the ion sources (3-1 to 3-4).
