METHODS OF ANALYSIS/SEPARATION

摘要

PURPOSE: The present invention relates to methods for separating particles based upon the migration of particles in response to an electric field. CONSTITUTION: Particles are separated according to their dielectrophoretic characteristics and electro rotation characteristics by the use of a traveling wave separation in which they flow from a departure point at an inlet (18) towards at least two destinations at outlets (16, 20) and are deflected toward one or other outlet according to their said characteristics by a traveling wave field set up on an array of electrodes, each electrode running generally in the direction of flow.
