Abstract

Laser-Induced Breakdown Spectroscopy (LIBS) systems can be used for both positive material identification (PMI) and quantification of elements in a variety of aluminum alloys and stainless steels. We compare performance of a compact LIBS system with a full-size desktop LIBS system and assess differences. Spectra were obtained from 18 standard samples and used to build a library for analysis. The calibration library, once built, was tested against both additional measurements on the standard samples and on scrap aluminum obtained from a local scrap yard. Analysis was performed using both individual shots and averaged sets of laser shots on the unknown samples.
