Abstract
The description refers to a process for the selective thinning of the size distribution of particles in a given particle collective, namely an aerosol, using virtual impactor technology. Here, a volume flow entraining the given particle collective is accelerated and a partial flow is tapped from the accelerated volume flow at an angle to the direction of acceleration. Said volume flow is returned free of particles to the volume flow of the non-accelerated part. The volume flow retained in the circuit entrains the fine size fraction. Volume flow acceleration is achieved by focusing by mens of a jet or similar.
