Abstract: To quantitatively analyze halogen oxoacids such as bromic acid and perchloric acid, an HPLC/MS in which a mass spectrometer is connected to the outlet of a column of a high performance liquid chromatograph (HPLC) is used, and by using a reverse-phase column having an ion exchange function as the column, as well as a mixed liquid of an ammonium formate buffer solution and acetonitrile as the mobile phase, gradient analysis in which the concentration of ammonium formate in ammonium formate/acetonitrile is increased is performed. Thereby, a common HPLC/MS apparatus configuration using no suppressor makes it possible to appropriately separate various halogen oxoacids and other components contained in a sample and to detect them at high sensitivity.
