An analysis has been performed of data on particle samplers obtained during 1984 at Rubidoux, California, and Phoenix, Arizona, by the US EPA, with emphasis on prediction of mass collected by the Andersen model 321A and Wedding inlet (previously GMW40CFM) PM/sub 10/ samplers. Recent interpretation of these data appears to fail to correct adequately for particle bounce, and to severely overestimate the FINE particle mass. The present study uses two completely different algorithms to make these corrections. The results obtained from these two approaches agree within a few percent, and lead to a prediction of the mass collected by the Wedding inlet within 7 percent. The Andersen 321A sampler, on the other hand, overcollects by as much as 34 percent. This analysis, if substantiated, would raise serious questions concerning the adequacy of the presently proposed Federal Reference Method for qualification of PM/sub 10/ samplers.
