Zeta Potential Analyzers

When colloidal particles are dispersed in a solution they become electrically charged due to their ionic and dipolar characteristics. Zeta potential is a measure of particles attraction or repulsion. If the particles acquire a large positive or negatve zeta potential, they repel each other and form a stable suspension. Solutions are generally considered stable if they have a zeta potential of more than +30mV or less then -30mV. It should also be noted that zeta potential is highly dependent on pH. The point at which zeta potential reads 0mV is called the isoelectric point. Zeta potential is important in industries such as ceramics, minerals processing, water treatment, pharmaceuticals etc.
