Abstract
An ion trap in which highly accurate isolation, ECD, and CID can be efficiently performed. A reaction cell and a mass spectrometer of the present invention include an ion-trap which has a plurality of rod electrodes and creates a multipole field, a means for generating a magnetic field in the axial direction of the ion-trap, a means for creating a DC harmonic potential in the axial direction of the ion-trap, and an electron source for introducing electrons into the central axis of the ion-trap. The identification ability is greatly improved compared with the prior art.
