Cascade impactor WikipediaA cascade impactor measures the reach range of a particulate substance as it moves through an opening with the use of aerosol.Cascade impactors are strictly measurementrelated devices. In addition to measuring the range of substances moved through an opening by aerosol, the impactor can also be used to determine the particle size of the distributed substance.AMMONIUM SULFATE CRYSTALLIZATION IN ANDERSEN AMMONIUM SULFATE CRYSTALLIZATION IN ANDERSEN CASCADE IMPACTOR SAMPLES A.
