Abstract
Disclosed is a process and device for facilitating the differentiation of particles in a medium. The particles, which belong to at least two different groups of particles, are enclosed in a chamber bounded by electrodes which produce a rotating electrical field. A means for producing two rotating electrical fields having opposite directions of rotation and variable rotational frequency is provided to be attached to the electrodes. The particles exposed to the rotating electrical field forces with opposite directions of rotation can be differentiated on the basis of their rotational behavior.
