The present invention discloses a particle classification device and a particle classification system. The particle classification device according to the present invention comprises: an inner electrode of a columnar shape; an outer electrode, disposed apart from the inner electrode so as to surround the inner electrode, for generating an electric field; and an aerosol supply part for supplying aerosol particles to a separate space between the inner electrode and the outer electrode, wherein the separate space, in which the aerosol particles are introduced into the particle classification device and flow, is tapered from the aerosol flow upstream toward the aerosol flow downstream, whereby it is possible to precisely measure the number of particles which are classified by the particle classification device, simplify the system configuration, and measure the number (generation amount), size and distribution of particles in a shorter time than conventional techniques because a process in which classified particles pass through a saturation part is omitted. |
