Abstract
Atomic emission spectroscopy of laser-generated plasmas can be used to analytically detect elements at ppm concentrations in harsh or radioactive environments. In this technique, a laser beam is focused onto the surface of a sample, the sample is vaporized and a high-temperature plasma is formed. Spectral analysis of the plasma light yields a determination of the elemental content of the original sample.
