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.Modern solid surface analysis with SurPASS
