<p>A particle classifying apparatus according to the present invention includes: a pillar-shaped inner electrode; an outer electrode surrounding sides of the inner electrode to be spaced apart from the inner electrode; an aerosol supply part and an air supply part which supply air and aerosol respectively to a separated space between the inner electrode and the outer electrode; and an air supply part, wherein the separated distance between the inner electrode and the outer electrode is smaller in a downstream portion than in an upstream portion of the aerosol flow. When using the particle classifying according to the present invention, there may be merits that the aerosol particles may be classified and collected by size even though a flow path of the aerosol becomes shorter; and also generation of a pressure difference is prevented by disposing a chamber on a particle discharge path, so that the particles may be evenly collected from all directions of the aerosol flow path.</p> |
