Abstract
An ion analyzer includes a reaction chamber into which precursor ions derived from a sample component are introduced, a radical irradiation unit that generates and emits a predetermined type of radicals, a standard substance supply unit that individually supplies kinds of standard substances to the reaction chamber, where activation energy of radical addition reaction is known for each of the kinds of standard substances, and the activation energies are different in magnitude, an ion measurement unit that measures an amount of predetermined product ions generated from precursor ions derived from the standard substance by irradiation with the radicals, and a radical temperature calculation unit that obtains an amount of radicals that caused the radical addition reaction from the amount of the predetermined product ions and obtains a radical temperature based on a relationship between the amount of the radicals obtained for each kind of standard substance and activation energy.
