A technique for assessing size-selective dust samplers using the APS and polydisperse test aerosols

Abstract This paper describes the development and application of an experimental system for the measurement of sampler efficiency values using polydisperse aerosols. The system was applied to the characterization of a number of respirable dust samplers. The results obtained were affected by small daily variations in the experimental system, which could not be entirely accounted for by known sources of experimental error.
