Electrokinetic Analyzer for Solid Surface Analysis: SurPASS Brochure

The SurPASS electrokinetic analyzer helps scientists in the fields of chemistry and materials science to improve and adjust surface characteristics and to design new specialized material properties e.g. for polymers, textiles, ceramics, glass or surfactants. This instrument enables the investigation of electrokinetic effects at the solid/liquid interface for solids of almost any size and shape.

By measuring the streaming potential or streaming current of macroscopic solids, the SurPASS provides the zeta potential as the primary information.

The zeta potential is an interfacial property that is of great importance for understanding the behavior of solid materials in many technical processes. It gives insight into the charge and adsorption characteristics of solid surfaces.
