Nonideal collection characteristics of single stage and cascade impactors.
Experimental studies of single stage and cascade impactors showed that bounce was severe for dry particles on dry solid surfaces. Oil drops on dry surfaces or dry particles on oil coated surfaces were collected as predicted by theory. While glass fiber media collection surfaces reduced particle bounce, the impactor collection efficiency characteristics were changed.
