The analytical capability of laser induced breakdown spectroscopy (LIBS) based on tea CO2 laser system

Abstract

This paper gives an overview of analytical capabilities of the laser induced breakdown spectroscopy (LIBS) system, based on Transversely-Excited Atmospheric pressure (TEA) CO2laser, and time-integrated, spatially-resolved detection, for the analysis of solid materials. The developed LIBS system is unique, and differs from the commonly used systems in two respects. The first one is the laser used as an energy source for plasma generation, and the second one is the applied non-gated detection scheme. Various types of materials were analyzed, from metals to biological samples, under different experimental conditions. The obtained results were critically evaluated and compared to the results obtained using commercially available LIBS that comprises Nd:YAG laser and time-gated detection.It was concluded that when it comes to detectability, precision and sensitivity, this simple and cost effective LIBS system may be regarded highly competitive to standard LIBS systems.Physical chemistry 2016 : 13th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 26-30 September 2016
