Abstract:

Laser-induced breakdown spectroscopy LIBS has been used for steel analysis for many applications. LIBS was used to confirm that the steel sample of interest is the correct steel type using linear correlation. Next, we attempted to identify trace carbon and sulfur in the steel sample using a standard LIBS laboratory setup. However, the most intense carbon and sulfur emission occurs in the vacuum ultraviolet region and, therefore, needs specialized spectrometer equipment. Interference from steel lines and the trace amounts of sulfur and carbon prohibit the use of atomic emission lines in the more easily accessible ultraviolet-visible-near infrared emission region.
