Determination of Theoretical Sampling Efficiencies for Aspirated Particulate Matter through the DRES Large-Volume Sampler

Abstract

Sampling and collection efficiencies are calculated for a large- volume air sampler under conditions of anisokinetic as well as isokinetic flow. A mathematical model developed to evaluate a tapered-tube sampling probe was modified to obtain results for the large-volume sampler, using various particle sizes and flow velocities. These results should facilitate the prediction or correction of sampling errors in field and laboratory experiments.
