Use the SurPASS™ 3 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-on-solid surface adsorption processes. SurPASS™ 3 helps you to understand and improve surface properties and to develop new specialized materials.

Modern solid surface analysis with SurPASS™ 3

  • High sensitivity for detecting the smallest changes in the surface properties
  • Easy access to information on surface charge and related properties
