The document summarizes industrial applications of laser-induced breakdown spectroscopy (LIBS). It discusses how LIBS has been used for metals and alloys processing like slag analysis, liquid steel analysis, and identification of pipe fittings by reducing analysis times by 40-50% compared to other techniques like XRF spectroscopy and spark OES. It also lists applications in scrap material sorting and recycling like segregating brominated and non-brominated plastics and sorting metal alloys and technical glasses by composition. The presentation concludes that LIBS is rapid, accurate, and reliable for these industrial analyses.

Variety of steel grades are used in these companies Mismatch in pipes can lead to corrosion with severe consequential damage Laser Identification of Fitting and Tubes (LIFT) is used. Superseded: Spark OES 7
