| Research Abstract |
An analytical system based on atomic emission excited by laser-induced plasma (LIP) was developed and employed for the element-based sorting of actual scrapped samples. An optimal experimental condition for the LIP system was investigated in time-resolved and modulation detections of their emission intensities. A sorting of stainless steels was conduced by estimating the contents of nickel, chromium, and molybdenum, in them, and also small amounts of copper in steel samples could be determined by using the LIP optical emission spectrometer.
