Multichannel electrophoresis apparatus employing electrophoretic light scattering as a means for characterizing the particles under study. The apparatus is characterized by the ability to measure light scattered simultaneously using a plurality of local oscillators incident at different angles from the same population of particles being subjected to electrophoresis. The apparatus is used with data processing means to analyze the large amount of scattering data which provide information on electrophoretic mobility, particle size, particle charge, electrophoretic mobility, zeta potential. An important aspect of the new apparatus is a markedly improved capability to segregate data related to diffusion effects from data relating to heterogeneous effects.
