Abstract: A mass spectrometry device that can perform highly robust, highly sensitive, and low-noise analysis and addresses the problems of preventing reductions in ion transfer efficiency and of suppressing the introduction of noise components from droplets, etc. An ion source generates ions, a vacuum chamber is evacuated by an evacuation means and for analyzing the mass of ions, and an ion introduction electrode introduces ions into the vacuum chamber. The ion introduction electrode has an ion-source-side front-stage pore, a vacuum-chamber-side rear-stage pore, and an intermediate pressure chamber between the front-stage pore and the rear-stage pore, the cross-sectional area of an ion inlet of the intermediate pressure chamber is larger than the cross-sectional area of the front-stage pore, the position of the central axis of the front-stage pore and the position of the central axis of the rear-stage pore are eccentric, and the cross-sectional area of an ion outlet of the intermediate pressure chamber is smaller than the cross-sectional area of the ion inlet.

Abstract: Provided is an ion source achieving high sensitivity and high robustness while executing a plurality of types of ionization schemes. To this end, a hybrid ion source (1) includes: a chamber (24); a first ion source (2) to spray a sample solution (5) for ionization; a second ion source (3) to ionize droplets and/or a gas component sprayed from the first ion source (2); a first electrode (11) to introduce a first ion (7) generated by the first ion source (2), and a second ion generated by the second ion source (3); and an exhaust pump (27) that generates air flow (26) in a direction from a first space area (23) where the first ion (7) is generated to a second space area (19) in the second ion source (3) where the second ion is generated.
