PROBLEM TO BE SOLVED: To provide a method and an apparatus for conducting electrophoretic measurement.SOLUTION: An electrophoretic measuring method comprises use of a container for holding a dispersant, a first electrode soaked in the dispersant and a second electrode also soaked in the dispersant. A sample is arranged in a position within the dispersant between the first electrode and the second electrode in a state separated from the two electrodes, an AC electric field is applied over the first electrode and the second electrode, and the sample is irradiated with temporally coherent light. A frequency shift is detected from light in an irradiating process during the step of applying the AC electric field, and characteristics of the sample are derived on the basis of the result of the detecting step.SELECTED DRAWING: Figure 2B |
