TY - JOUR A1 - Gornushkin, Igor B. A1 - Panne, Ulrich A1 - Winefordner, J. D. T1 - Linear correlation for identification of materials by laser induced breakdown spectroscopy: Improvement via spectral filtering and masking JF - Spectrochimica acta B N2 - The purpose of this work is to improve the performance of a linear correlation method used for material identification in laser induced breakdown spectroscopy. The improved correlation procedure is proposed based on the selection and use of only essential spectral information and ignoring empty spectral fragments. The method is tested on glass samples of forensic interest. The 100% identification capability of the new method is demonstrated in contrast to the traditional approach where the identification rate falls below 100% for many samples.
