Abstract

A study of gaseous sulfur dioxide detection in air by Laser Induced Breakdown Spectroscopy(LIBS) is reported. Plasmas were formed in the sulfur dioxide gas, and three lines of sulfur at 560.61nm, 567.77nm and 565.99nm were observed. We found that the most appropriate experimental conditions for LIBS detection on sulfur dioxide gas are: Laser Pulse Energy =100mJ, Gate Time Delay = 2us. A further study was made in detecting sulfur dioxide gas of different concentrations by LIBS. Finally we calculated the detection limit of sulfur dioxide gas is 330ppm.
