PARTICLE-SIZE DETERMINATION OF AEROSOLS BY THE PHOTOEXTINCTION TECHNIQUE
Abstract
A photoextinction method has been developed to determine particle- size distributions of setting aerosols in a large test chamber. The theory of photoextinction by aerosol particles were explored and applied to a method of determining particle-size distributions from decay measurements based on Stokes' law. A photometric measuring apparatus was constructed and installed in the testing facility. Measurements of changes in light transmission were made for several dissemination experiments. Data reduction procedures were investigated with the data obtained. Errors in both theory and measuring instrumental parameters are discussed.
