Electrokinetic Analyzer for Solid Surface Analysis: SurPASS™ 3

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.

Key Features

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

From tiny particles to large wafers

  • Different measuring cells for flexible sample mounting
  • Cylindrical Cell for powders (min. particle size 25 µm ) and fibers
  • Clamping Cell for non-destructive measurement of planar solids
  • Adjustable Gap Cell for small samples (20 mm x 10 mm, 14 mm dia., 15 mm dia.)

Short downtimes

  • Quick exchange of measuring cells
  • Recording of measuring data at > 5 Hz
  • Intuitive software with clearly arranged data display

Fully automated measurements

  • Automated measuring procedures require little manual interaction
  • An integrated titration unit provides fully automated adjustment of pH and additive concentration
