Abstract
A mass spectrometry device that is provided with an ionization unit and ionizes, by the ionization unit, a sample separated by a separation column, subjects the sample to mass separation and detect ions obtained in the mass separation, includes: a gas introduction unit that introduces a first gas obtained by vaporizing a liquid into the ionization unit using a second gas, wherein: the ionization unit ionizes the sample by reacting ions obtained by ionizing the first gas with the sample.
