Abstract

Very little instrumentation exists to characterize individual ultrafine aerosol particles. A thermophoretic precipitator has been developed to deposit uniform aerosol samples onto transmission electron microscope grids. Details are given of the precipitator's design, and preliminary results using an ultrafine silver aerosol are presented. Comparison of data from samples collected by thermophoresis and diffusion indicates a positive collection ability at nm particle sizes, but at lower deposition velocities than predicted.
