Abstract
The performance of a size selective air sampler, the cascade centripeter, for use as an instrument for sizing solid airborne particles has been investigated using unit density spheres of methylene blue and denser non-spherical particles of silicon carbide and uranium oxide. It has been demonstrated that the instrument can be used to determine the particle size distribution of airborne particulates, irregular in shape, over a wide range of density. Effective cut-off sizes are rccommanded as characteristic for the respective collection stages. In terms of unit density spheres, Stage 1 is defined as collecting all particles larger than 12.5 μm, Stage 2 to collect particles in the range 12.5–4.0 μm, Stage 3 to collect particles in the range 4.0–1.5 μm and the final filter paper to collect particles of less than 1.5 μm dia.
