The study of Zeta Potential (ζ) property allow the user to understand the stability of colloidal suspensions and provide insight on the adhesion between solid materials. In addition, Zeta potential parameter is important to determine the adsorption and chemical reaction of surfactants, molecules, ions, polymers with the solid surface.

The behaviour of the interface between solid and liquid sample can be characterised by measuring the Zeta Potential. Parameters such as isoelectric point and the adsorption kinetic of the solid can be further derived from zeta potential analysis.

DataPhysics Instruments had patented a Worlds first bidirectional oscillating streaming potential analysis. It is a measuring technique which uses an oscillatory flow of electrolyte solution through or along the sample. The instrument measures the streaming potential, the currently applied pressure, as well as the temperature, conductivity and pH value of the electrolyte solution. By applying a wide range of flow frequencies and amplitudes, a rapid and precise measuring results can be obtained.

DataPhysics has developed the compact Zeta Potential Analyzer ZPA 20 which is utilizing this patented bidirectional oscillating streaming potential method.
