PURPOSE:To perform an easy, rapid, and high-precise analysis, by a metod wherein a sample housed in a fire resistant crucible is fused by a high frequency heating to evaporate it into a metallic fine particle, which, in turn, is conveyed by a gas carrier to an emission spectrochemical analyzer having a plasma exciting source. CONSTITUTION:A sample metal 3, housed in a fire resistant crucible 4 in an enclosure cylinder tube 2 of a fine particle generator 1, is heated and fused by a high frequency induction heater 6, and a metallic fine particle is evaporated from the surface. A given quantity of the fine particle is conveyed by a gas carrier through a conveyance gas distributor 17 to an emission spectrochemical analyzer 19 provided with a plasma exciting source to produce a plasma flame 23, and a component quantity of an analysis sample is measured from a spectral line strength by means of a spectrum. After a component quantity is measured, a cleaning is conducted by a high velocity of flow gas carrier. The constitution, almost eliminating the need for hands, permits the easy, quick, and high-precise analysis of a metal material. |
