を特徴とする四重極型質量分析計。[Claims for Utility Model Registration] A quadrupole configured to inject ions generated by an ion source between quadrupole electrodes and detect the mass number by sweeping the voltage supplied to the quadrupole electrodes. In a type mass spectrometer, the range for detecting mass numbers is divided into multiple sections,
a sweep setting unit that presets a sweep voltage for detecting ions having a mass number existing in each of the divided sections; and an energy of ions that are incident from the ion source between the quadrupole electrodes for each of the divided sections. and a voltage setting section that presets the voltage supplied to the ion source that determines the incident condition, and when sweeping a predetermined divided section using one of the sweep voltages preset in the sweep setting section. A quadrupole mass spectrometer, characterized in that the voltage setting section supplies a voltage corresponding to the divided section to an ion source.
