Abstract

For several years the laser-induced breakdown spectroscopy (LIBS) technique has been applied successfully to the problem of detecting small traces of pollutants in gases. The possible application of this method for the individuation of mercury in air is discussed. The laboratory prototype of the detection system is described in detail, and the sensitivity of the system for the diagnostics of small traces of mercury is determined. The reduced dimensions of the experimental apparatus and its relatively low cost make the LIBS method competitive with other laser-based methods for in situ analysis.
