Patent ID: 7710562

Claim:
An atomic analyzer, comprising: a plasma generator in which a discharge gas is fed in a micro gap between a pair of electrodes to generate nonequilibrium atmospheric pressure plasma; a bias voltage controller that includes a plasma-leading electrode for leading the nonequilibrium atmospheric pressure plasma generated by the plasma generator to an object to be irradiated, the object to be irradiated with the nonequilibrium atmospheric pressure plasma being placed on the plasma-leading electrode, a bias voltage being applied between the plasma-leading electrode and the electrodes of the plasma generator to irradiate the object with the nonequilibrium atmospheric pressure plasma; and a spectrometer that analyzes the atoms spectroscopically from light emitted from atomized atoms generated by atomizing a substance composing the object to be irradiated by the nonequilibrium atmospheric pressure plasma irradiation or from light absorbed by said atomized atoms.
