Abstract:
1. An electrophoretic mobility measurement cell comprising: a container having a rectangular parallelepiped internal space for introducing a sample solution; at least two electrodes formed in the interior of the container and configured to apply an electric field to the internal space; a tubular sample injection portion in communication with the internal space; a tubular sample extraction portion in communication with the internal space; a first cap for covering the sample injection portion and sealing the internal space; and a second cap for covering the sample extraction portion and sealing the internal space; and wherein the at least two electrodes are U-shaped or S-shaped, wherein the first cap has a first side surface that contacts an inner side surface of the tubular sample injection portion when the first cap is mounted, and wherein the inner side surface of the tubular sample injection portion is formed so that an inner cross-sectional area of the tubular sample injection portion increases with distance apart from the internal space, and an area of a cross section of the first side surface decreases gradually in the direction of insertion of the first cap.
