Development of new methods and apparatus for industrial elemental analysis



A goal of our research is to develop new instrumental methods in quantitative elemental analysis. We have suggested a new analytical method enabling trace elements at a few ppm level to be directly determined. We now study analytical applications of a low-pressure laser induced plasma as well as a glow discharge plasma associated with laser ablation, in order to carry out rapid analysis for the process control in material industries and for selection of scrapped materials.

Targeted Application(s)/Industry

Industry: We have already conducted cooperative research on industrial analyses with several metal-making companies as well as the iron and steel institute of Japan. We also hope cooperative works on practical analysis in various manufacturing fields.
