Abstract
The goal of this research project was to design and construct a particle sizing device that will collect and size source emitted aerosols on 47 mm diameter substrates for subsequent wavelength dispersive x-ray fluorescence analysis. Calibration studies were conducted with a prototype unit designed to allow various slit widths and jet to plate spacings. These studies provided the design criteria used for dimensioning the final impactor. With this sampling system samples can be readily collected which can be directly analyzed by wavelength dispersive x-ray fluorescence analysis for elemental composition. No sample preparation will be required other than mounting the substrate in a carrier for the analysis.
