Abstract

The analysis of air for traces of poisonous metals usually involves passing large volumes of air through filters or absorbing solutions followed by extensive manipulation before actual analysis. In order to simplify these analyses, several workers have reported upon the measurement of airborne particulates filtered onto spectroscopic electrodes. Woodriff and Lech draw air through porous graphite cups which then are inserted into a graphite furnace atomizer. Analysis of lead particulates at levels present in the atmosphere can be accomplished on only 50 cc of air. Amos and co-workers have described application of the carbon rod atomizer to the analysis of lead in air. An essentially standard cup is perforated through the bottom with many small holes. A disc of Millipore filter media is placed into the cup (à la Buchner funnel), and air is drawn through. The cup is then placed into the atomizer, the filter is ashed off, and the lead is atomized in normal fashion.
