Streaming potential & zeta potential meter
(Zeta potential for powder, solids, polymer, membrane, fiber etc...)
ZetaCAD is a specially designed automated equipment for the determination of Zeta Potential using the streaming potential technique
Principle
 | An electrolyte is to move through a capillary or porous plug by a pressure gradient. The excess charges around the particles or wall are carried along by the liquid. Their accumulation down stream causes the build-up of an electric field which drives an electric current back (by ionic conduction through the liquid) against the direction of the liquid flow. A steady state is quickly established and the measured potential across the capillary is called the streaming potential |
| Applicable to particles above 50 µm diameter and flat surfaces. |
| Reliable and simple to setup. |
| Measurement and rinsing of the system are fully automated. |
| Menu driven software Windows based. |
| Data acquisition creates ASCII files directly compatible with usual spreadsheet. |
