Electrokinetic Analyzer for Solid Surface Analysis:

SurPASS™ 3

SurPASS™ 3 is a high-end electrokinetic analyzer featuring fully automated zeta potential analysis of macroscopic solids in real-life conditions. SurPASS™ 3 employs the classic streaming potential and streaming current method for a direct analysis of the surface zeta potential. The zeta potential is related to the surface charge at a solid/liquid interface and is a key parameter for understanding surface properties and developing new specialized materials. Automatic pH scans and time-dependent recording of adsorption kinetics allow for a deep understanding of the surface chemistry.
