Abstract: PURPOSE: To simplify the alignment of optical axes by providing a groove on the surface of one of a pair of plate-shaped members, providing a through hole in the surface of the other member and in a position approximately corresponding to the groove, and bonding the members together with the groove inside. CONSTITUTION: A pair of plate-shaped members 1a, 1b, in which traps 5 to 5"' and migration grooves 2, 3 are filled with an analytical material and a buffer solution, is prepared. Needlelike electrodes are inserted into through holes 6 to 6"' in the plate-shaped members, and a light source portion and a light receiving portion are connected to flanges 9, 10, respectively. A predetermined potential difference is imparted to the traps 5, 5' to force the analytical material to flow through the groove 3, and the analytical material is injected into the groove 2. Next, a predetermined potential difference is also imparted to the traps 5", 5"' to cause the analytical material to migrate within the groove 2 from the trap 5' to the trap 5"'. During the migration process, light is applied to a cell portion 4 from an impinging optical fiber 7.  The light applied undergoes multiple reflections on the interior wall of the cell portion 4 and is transmitted to an outgoing optical fiber 8. The analytical material absorbs the light at the cell portion 4, and difference in intensity of the light appears, and the separation is confirmed. Thus, the optical fibers are buried in the light source and light receiving sides, so the necessity of fine adjustments for the alignment of optical axes is eliminated.
