Paper Abstract

Laser-induced breakdown spectrometry (LIBS) is a non-contact in-situ method for the chemical analysis of various materials. Our R&D activities concentrate on the improvement of the analytical features of LIBS for the quantitative multi- elemental analysis of low-alloyed steel grades. The analytical sensitivity for the crucial elements C, S, and P, but also for Mn, Si, Cr and Ni was enhanced significantly. The limit of detection achieved for these elements is below 10 (mu) g/g. For low alloyed steel, the analytical performance of LIBS has now achieved for most elements the level of conventional laboratory based methods such as spark-discharge optical emission spectrometry (SD-OES).
