Abstract
PURPOSE:To improve sensitivity and accuracy by transferring the vapor generated from sample surface by laser by means of a high-purity gas. CONSTITUTION:A gas inlet part 4 and a torch 9 are provided to a sampling part 6, and said part is passed through a waveguide 10 connected to a microwave power source 8. A spectral part 13 is disposed to the torch 9 via a photometric condensing system 12. The leser light 11 from a laser oscillator 2 is irradiated to the sample on a sample table 7, and the vapor generated is introduced into the torch 9 by the high-prity gas from the gas inlet part 4, so that it is allowed to collide against the previously introduced high-purity gas having been activated to plasma flame by the microwave of the waveguide 10, whereby plasma cloud 18 of the generated steam is formed. The light generated by the transition from this plasma excitation state to a ground state or metastable state is divided by the spectral part 13 and is detected with a detecting part 14. Thereby, the diffusion of the stained sample measuring surface by the electrode at the auxiliary exciting of the atom vapor generated from the same surface and the mingling of the atom vapor and the plasma state are eliminated and the measurement of high sensitivity and high accuracy is made possible.
