Electrokinetic measurements four types

Electrokinetic Phenomena. Electrokinetic motion occurs when the mobile part of the EDL is sheared away from the inner layer (charged surface). There are four types of electrokinetic measurements, electrophoresis, electroosmosis, streaming potential, and sedimentation potential, of which the first finds the most use in industrial practice. Good descriptions of practical experimental techniques in electrophoresis and their limitations can be found in references 18-20. 

There are four basic types of electrokinetic techniques that can be used to evaluate the zeta potential under a given set of conditions. The common feature of these electrokinetic measurements is the relative motion between a charged surface and its surrounding fluid, with an electric field either applied or generated from the movement. Perhaps the most familiar type and most widely used electrokinetic technique is electrophoresis, which involves the movement of charged particles under the influence of an applied electric field [28].
