Abstract : This report covers work conducted under a Phase I SBlR program to develop, fabricate, and deliver a Laser-Induced Breakdown Spectroscopy analyzer. This analyzer is capable of measuring the concentration of lead in contaminated soil and on painted surfaces. Work during the contract involved defining design and performance parameters for the instrument, identifying and ordering component parts, and assembling and testing the analyzer. The analyzer was tested using a series of soil calibration standards containing known concentrations of lead. Quantifiable signals were obtained for soil containing 247 ppm lead. This compares well against the screening action level for contaminated soils of 400 ppm. An operating and maintenance manual was written for the instrument. Los Alamos National Laboratory provided technical support during the project. Phase II work will involve enhancing the performance of the instrument to include the ability to quantify a number of additional metals. The Phase II instrument will be evaluated at contaminated sites.
