In a Raman spectroscopic system: a sample cell in which a sample is filled or through which the sample flows down, where the sample has fluidity and contains one or more materials being to be measured, and having an electrophoretic feature or being conditioned in advance so as to have an electrophoretic feature; a Raman scattering device which has a sample-contact surface, is arranged so that the sample is in contact with the sample-contact surface, and outputs Raman-scattered light when the sample-contact surface is illuminated with measurement light; an optical system which illuminates with the measurement light the sample in contact with the sample-contact surface; a voltage application unit which is provided with the sample cell and applies an electric voltage to the sample so as to bring the one or more materials close to the sample-contact surface by electrophoresis; and a detection unit which detects the Raman-scattered light.
