Scope

This part of GB/T 32671 specifies two methods for measuring the electrophoretic mobility of suspended particles in liquids: microscopic imaging and electrophoretic light scattering. The estimation of particle surface charge and the determination of zeta potential can be obtained by measuring electrophoretic mobility and using appropriate theoretical models. Note: For related theories, please refer to ISO 130991.
