ABSTRACT:
A plurality of types of liquid with different electrical conductivity flow through a micro channel having a plurality of channels. When an electric field is applied thereto, an electrokinetic driving flow generated in the micro channel attracts objective submicron particles to one side. Therefore, the particles are completely separated in a single operation by use of the micro channel having extremely simple structure, without the necessity of special machining of the channels and the like.
