摘要： PROBLEM TO BE SOLVED: To solve the problem that a conventional MS/MS method cannot compatibly attain throughput and precursor ion mass resolution.
SOLUTION: This mass spectrometer includes an ion trap for discharging ions in a specified mass range, a collision dissociation part for dissociating the ions discharged from the ion trap, and a mass spectrometric part for performing the mass spectrometry of the ions discharged form the collision dissociation part. It resonantly discharges the ions introduced and accumulated into the iron trap in a mass selective manner. It measures the precursor ions in the conditions that incident energy into the collision dissociation part is low, and acquires a set of the profile of the precursor ions at the mass axis of the ion trap part and the profile thereof at the mass spectrometric part. Then, it measures the precursor ions in the conditions that incident energy into the collision dissociation part is high, and replaces the profile at the mass axis of the mass spectrometric part with the profile of the precursor ions of the obtained two-dimensional mass spectrum at the mass axis of the iron trap part. In this method, m/z of each of the precursor ions and fragment ions can be determined with high mass resolution.
