摘要

The single charge primary ions are dissociated so as to form the neutral fragment and charged fragment pair. A predetermined electrical and magnetic fields are applied to the fragment pairs based on the mass to change the times of the flight of the charged fragments. The time of flight and the position of the arrival of the fragments are determined, and the fragment pairs in the measured positions and measured times of the flight, which reached the detector are identified. The different dissociation spectra comprising the charged fragments is generated. Independent claims are included for the following: (1) tandem and time of flight mass spectrometer; and (2) three dimensional mass spectrum.
