PROBLEM TO BE SOLVED: To provide an ICP analysis device that has a self-oscillation-type high-frequency power source and can determining the type of a mounted plasma torch.SOLUTION: An ICP analysis device 100 includes a self-oscillation-type power supply unit 120 for supplying a high-frequency power for plasma generation to an induction coil 111 wound on a plasma torch 110. The ICP analysis device includes: a frequency measurement unit 121 for measuring an output frequency of the power supply unit 120; a storage unit 190 in which a reference output frequency for each type of plasma torch is stored; and a torch determination unit 132 that determines and reports whether a measured output frequency after lighting up of plasma measured by the frequency measurement unit 121 matches with any of reference output frequencies. Thus, the ICP analysis device can determines the type of the plasma torch 110.SELECTED DRAWING: Figure 1 |
