An ICP analyzer 100 includes a self-oscillation radio-frequency power supply unit 120 for supplying radio-frequency power for generating plasma to an induction coil 111 wound around a plasma torch 110. To check the type of plasma torch 110, the analyzer 100 further includes: a frequency measurement section 121 for measuring an output frequency of the power supply unit 120; a storage unit 190 holding a reference output frequency for each type of plasma torch; and a torch checker 132 for determining whether or not the output frequency measured by the frequency measurement section 121 after the plasma is lit agrees with any one of the reference output frequencies, and for giving notification of the determination result.
