Collection Efficiency of the Rotorod FP Sampler

Abstract

Reported are the results of 28 small-scale field trials run to investigate the collection efficiency of the Rotorod FP sampler, a low-cost impaction sampling device now widely used for the collection of 1-5 micron FP atmospheric tracer aerosols. Since the high impaction speed of the Rotorod is essentially constant over a wide range of wind speeds, its collection efficiency is primarily a function of the particle sizes comprising the tracer aerosol to be sampled. From 4-8 trials were run with each of 6 different lots of FP tracer material in order to investigate the dependency of collection efficiency on particle size; the mass-mean diameters (MMD) of these 6 lots ranged from 1.8 - 3.8 microns.
