Fig. 1. (A) Region of laser-induced breakdown spectroscopy (LIBS) spectrum from 245 to 250 nm showing C and Fe interferences at approximately 248 nm. The line intensity of C cannot be quantified independently from the Fe line, and this interference increases as Fe concentration increases. (B) Region of LIBS spectrum showing C line at 193 nm, Al at 199 nm, and Si at 212 nm. The C line is easily quantified without interference from other elements. Aluminum and Si lines were also easily quantified and were used as standardizing factors.
