Paper Abstract

Laser induced breakdown spectroscopy (LIBS) is being used to detect heavy metal concentrations in soils. The overall goal of this effort is to develop a field deployable system that will conduct heavy metal subsurface mapping of the vadose zone using a cone penetrometer deployed fiber optic sensor. This paper presents results on the LIBS analysis of different spiked soil samples with the same chemical matrix, NIST soil samples with variable matrices, a comparison of the performance of the LIBS system with free space delivery of the laser beam versus the performance using an optical fiber probe, and the effect of several system parameters on performance.
