Abstract:
A portable instrument for automatic collection and analysis of airborne lead concentrations in ambient air environments. Its improvements to the art of airborne lead detection and analysis permit the apparatus to analyze samples previously collected by personal monitors, for example, worn on the clothing of personnel working in contaminated sites. The apparatus also brings to the art of lead analysis a method of contaminant collection that ensures a greater capture efficiency of airborne contaminants, thereby increasing the accuracy of the instrument and its measurement capabilities while providing near real-time analysis and measurement in a portable self-contained battery-powered device. The apparatus also offers a remarkable improvement in the reduction of wastes incurred in the collection and analysis of airborne lead contaminants which is a novel method of concentrating the samples and recycling the analysis media used to concentrate and solubilize lead contaminants.
