Your gateway to solid surface charge analysis
SurPASS™ 3 Eco is the entry-level instrument for routine surface analysis featuring fully automated zeta potential measurements of macroscopic solids at real-life conditions. SurPASS™ 3 Eco employs the classical 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 the solid/liquid interface and is a key parameter for understanding surface characteristics and developing new specialized materials.
