Abstract

A field-deployable analyzer for the determination of metals in soils is described. The instrument is based on laser- induced breakdown spectroscopy (LIBS), a form of atomic emission spectroscopy. In the LIBS technique, powerful laser pulses are focused on the soil to form a series of microplasmas that vaporize and excite the elemental constituents of the soil. The plasma light is spectrally analyzed to determine the elemental composition. The results of an initial field test of the instrument are described and a brief critique of the results presented.
