摘要

梯队式光谱仪，还有ICCD探测器。考虑到合金中铁基体发射谱线的干扰，可以选择波长为324.754 nm和327.396 nm的Cu I谱线。在对每个SRM的5次重复测量中，建议较短的激光照射后延迟时间和较长的检测瞬态发射信号的门宽是最佳的实验参数。

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

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.
