Abstract
A mass spectrometer including: a reaction chamber into which a precursor ion derived from a sample molecule is introduced; a collision gas supply part configured to supply collision gas to the reaction chamber; a radical supply part configured to supply hydrogen radicals, oxygen radicals, nitrogen radicals, or hydroxyl radicals to the reaction chamber; a dissociation operation control part configured to control operations of the collision gas supply part and the radical supply part to generate the product ions by collision-induced dissociation and radical attachment dissociation of the precursor ion inside the reaction chamber, an ion detection part configured to mass-separate and detect ions ejected from the reaction chamber, and a spectrum data generation part configured to generate spectrum data based on a detection result by the ion detection part.
