Abstract

A method and apparatus for determining the zeta potential of particles in a suspension comprising: a cell containing at least a portion of the suspension of particles; a first electrode and a second electrode disposed in a cell; means for producing an electric field between the first and second electrodes, the electric field causing the particles to accelerate; means for converting a force, the force being generated by the acceleration of the particles, into electrical energy; and means for measuring the electrical energy.
