Abstract

PURPOSE:To make a highly sensitive and precise spectroanalysis, by narrowing a plasma of sample vapor in accordance with a composition component and also, producing through a waveguide part equipped with a short circuit board effectively. CONSTITUTION:Sample vapor is generated from a sample 6 in accordance with a composition componet by laser light irradiation and is conveyed in a torch 9 penetrating a waveguide 13 through carrier gas. Then, a plasma flame 21 of the sample gas is formed by microwave energy propagating the waveguide 13. Movable short circuit boards 121, 122 and a throttle 14 are provided to the waveguide 13 and then, the microwave energy from a magnetron 11 propagating in the waveguide 13 is adjusted. The plasma flame formed by the sample gas is produced effectively and a highly sensitive and precise spectroanalysis performed.
