Electrokinetic Analyzer for Solid Surface Analysis: SurPASS

Use the SurPASS electrokinetic analyzer in surface analysis to investigate the zeta potential of macroscopic solids based on a streaming potential and streaming current measurement. The zeta potential is related to the surface charge at a solid/liquid interface and is a powerful indicator for the surface chemistry (pH titration) and liquid phase adsorption processes. SurPASS helps you to understand and improve surface properties and to develop new specialized materials.
