Aerosol classification by dielectrophoresis: a theoretical study on spherical particles.

ABSTRACT: The possibilities and limitations using dielectrophoresis (DEP) for the dry classification of spherical aerosol particles was evaluated at low concentrations in a theoretical study. For an instrument with the geometry of concentric cylinders (similar to cylindrical DMA), the dependencies of target particle diameter [Formula: see text], resolution, and yield of the DEP classification on residence time, applied electric field strength, and pressure of the carrier gas were investigated. Further, the diffusion influence on the classification was considered. It was found that [Formula: see text] scales with the mean gas flow velocity [Formula: see text], classifier length L, and electric field strength E as [Formula: see text]. The resolution of the classification depends on the particle diamet
