ABSTRACT:
A collecting device for collecting suspended particles includes a mobility analysis device; a collecting container connected to an outlet of the mobility analysis device; a discharge electrode disposed inside the collecting container for charging the particles inside the collecting container by generating single polar ions; and a collecting electrode for collecting the charged particles inside the collecting container by an electric potential difference relative to the discharge electrode. In the mobility analysis device, the particles are charged and guided into a flow path. An electric field is created in the flow path, and the particles are guided into the path perpendicular to the electric field. Since a mobility of a particle in an electric field depends on a size of the particle, the particles guided in the path are separated according to the electric field, thereby obtaining particles with sizes in a specific range.
