Abstract
A method and apparatus are disclosed for measuring interfacial electrokinetic phenomena such as electrophoresis by applying stationary electric field to a sample, wherein the voltage between two points in the sample other than the electrodes for an electric current application is detected and the electric current is supplied to the sample to maintain the detected voltage constant, and the sample is preheated while the particles being substantially kept in a stationary state by applying an alternating voltage prior to the application of the stationary voltage, to thereby obtain the mobility of the charged particle in the sample at high accuracy.
