Bounceless high pressure drop cascade impactor and a method for determining particle size distribution of an aerosol

摘要

This invention is directed to a high pressure drop cascade impactor wherein the particles do not bounce from the collection plate; to a method for designing said impactor; a method for calculating and determining the particle size distribution of an aerosol wherein the particle size may have a Stokes (aerodynamic) diameter as small as 10 nanometers; and, to a method of manufacturing such an impactor.
