Zeta Phase Analysis Light Scattering (Zeta PALS)

The Zeta PALS determines zeta potential using Phase Analysis Light Scattering: A technique that is up to 1,000 times more sensitive than traditional light scattering methods based on the shifted frequency spectrum. Electrostatic repulsion of colloidal particles is often the key to understanding the stability of any dispersion. A simple, easy measurement of the electrophoretic mobility “even in nonpolar liquids” yields valuable information. Measurements made in water and other polar liquids are easy and fast with the ZetaPlus. Such measurements cover the range of typically 9 – 100 mV, corresponding to a range of mobilities of 0.5-8 x 10-8 m²/V s
