Laser-Induced Breakdown Spectroscopy, or LIBS, is a laser-based form of atomic emission spectroscopy that can be used for the in-situ elemental analysis of coal gasifier product streams. At this point, LIBS has been deployed in three gasifier field tests, and C, H, O, N, Na, K, S, Cr, Cu, Fe, Mg, Pb, Se, Al, Ba, Ca, Cd, Li, and Mn were qualitatively detected in the various product streams. In laboratory experiments on quantitative detection, a detection limit of 4 ppB was demonstrated for sodium. The long-range goal of this program is add the trace elements As, B, Mo, Ni, V, and Zn to the detection list, and to develop the capability of quantitative detection in real time for the trace elements. 4 figures.
