Abstract
Disclosed is a process and device for facilitating the differentiation of particles in a medium. The particles are exposed to a rotating electrical field of variable rotational frequency. By providing a means for adjusting the frequency of the rotating fields, the particles can be caused to rotate in different directions thereby facilitating differentiation of particles belonging to different groups of particles. An apparatus for implementing this process includes at least three electrodes which are arranged so as to form a space therebetween. A device for producing a rotating field of variable rotational frequency is connected to the electrodes.
