The SurPASS electrokinetic analyzer enables the zeta potential measurement for macroscopic solids of almost any size and shape, including samples with planar surfaces, cylindrical capillaries, and packed beds of granular or fibrous materials. Measurements are fully automated and non-destructive. An excellent level of reproducibility is achieved due to the high sensitivity of the measuring device. Applications include the fields of semiconductors, biomaterials, textiles, and technical fibre research. Beside other investigations, the SurPASS allows monitoring of polymer surface modifications for printing and adhesion, or gives an insight into the effect of surfactants or dyes on textile and non-woven fabrics.
SurPASS – Zeta Potential of Solid Surfaces
The zeta potential of fibres and powders is determined using the Cylindrical Cell. A clever-designed mechanism enables highly reproducible sample mounting.
