Laser-Induced Breakdown Spectroscopy (LIBS) has been used to monitor the metal concentrations of the off-gas system of a 250 kW plasma treatment system during vitrification of a Savannah River surrogate waste. LIBS spectra of different elements in the off-gas emission have been recorded in various spectral regions to select the appropriate spectral lines for the concentration measurements. The LIBS concentration measurement were then performed at different test run conditions. The results of various measurements are presented. These measurements demonstrated LIBS`s capability for real-time toxic metal monitoring.
