Laser Induced Breakdown Spectroscopy for Rapid Delineation of Metals in Soils

Abstract

The development of a metal sensor that can be deployed with a cone penetrometer for in-situ subsurface measurements is described. The sensor utilized Laser Induced Breakdown Spectroscopy (LIBS) to analyze the atomic emission of metals on contaminated soil samples. The novel approach taken in this work is that the measurements are done remotely with both laser excitation and signal collection transmitted through fiber optic cables.
