PURPOSE:To increase the detection limit value in plasma emission spectrochemical analysis, by making atoms in ground state generated by plasma excited with an exciting light source to increase the intensity of the emission from the excited state. CONSTITUTION:In emission spectrochemical analysis using a plasma 2 as light source, a light source 1 for atomic excitation is provided. The light source 1 herein used is, for example, hydrogen lamp or Xe lamp as continuous light source. As the result, the number of atoms excited increases by a plasma excitation end light excitation. This can increase detection limit value in the plasma emission spectrochemical analysis.
