Zeta potential

Also ζ-potential, is the electrical potential at the contact layer of a moving particle with an aqueous solution (suspension). Thus, within the same suspensions, it is a relative measure of the surface potential and thus the charge of the particle. For the measurement of the zeta potential, charged particles are moved through an applied electric field. The resulting speed is then a measure of the zeta potential.
