ORTHOGONAL AND COLLINEAR CONFIGURATIONS OF DOUBLE PULSE LASER INDUCED BREAKDOWN SPECTROMETRY FOR SENSITIVE CHLORINE ANALYSIS
Abstract
We have considered collinear and orthogonal configurations of double-pulse laser-induced breakdown spectrometry (LIBS) for the chlorine determination in plants and concrete by Cl I 837.59 nm line. It has been found that the signal-to-noise ratio is slightly lower in the orthogonal configuration due to spatial instability of the second breakdown. At the same time, the suppression of interfering molecular bands in this case can increase the LIBS sensitivity of chlorine analysis in plant materials.
