Claim 0:
1. An ion analyzer for analyzing product ions generated by irradiating precursor ions with a predetermined kind of radicals, the precursor ions being derived from a sample component, the ion analyzer comprising:
a reaction chamber into which the precursor ions are introduced;
a radical irradiation unit configured to generate the a-predetermined kind of radicals and emit the predetermined kind of radicals to an inside of the reaction chamber;
a standard substance supply unit configured to supply a plurality of kinds of standard substances to the reaction chamber, where respective activation energies of reactions of the predetermined kind of radicals with each of the plurality of kinds of standard substances are known, and the activation energies are different in magnitude;
an ion measurement unit configured to measure an amount of predetermined product ions generated from precursor ions derived from each of the plurality of kinds of standard substances by irradiation with the predetermined kind of radicals; and
a radical temperature calculation unit configured to obtain an amount of the predetermined kind of radicals that caused a radical addition reaction based on the measured amount of the predetermined product ions and obtain a radical temperature based on a relationship between the amount of the predetermined kind of radicals obtained for each of the plurality of kinds of standard substances and the activation energies.
