The Application of Laser-Induced Breakdown Spectroscopy on the Elementally-Based Sorting of Steel Scrap

Abstract

Echelle-type spectrometer, and an ICCD detector. Considering spectral interferences from the emission lines of the iron matrix in the alloys, Cu I lines having wavelengths of 324.754 and 327.396 nm could be chosen. In fi ve replicate measurements of each SRM, shorter delay times after laser irradiation and longer gate widths for detecting the transient emission signal are suggested to be the optimal experiment parameters.
