Title:
MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2016/174990
Kind Code:
A1
Abstract:
A mass spectrometer (11) according to the present invention, in order to control ion transmittance (sensitivity), comprises an ion source (2) that ionizes a sample, an ion guide (3) that comprises at least four rod-shaped electrodes and that transports ions, and a mass spectrometer unit (4) that comprises at least four rod-shaped electrodes that perform mass separation, a detector (5) that detects ions that passed through the mass spectrometer unit (4), and a control unit (8) that controls a voltage applied to the ion guide (3), wherein the control unit (8) fluctuates the passing energy of ions passing through the ion guide (3) in accordance with characteristics of the ions set as a target.
