Abstract:
1. An electrophoretic apparatus comprising: an electrophoretic member in which a plate-shaped member thereof has one or a plurality of passages formed therein and also such holes reaching the passage that are formed at positions corresponding to both ends of the passage on one surface of the plate-shaped member, each of the passages comprising a specimen-injection-passage and a separation-passage which intersect with each other; a voltage applying part for applying a voltage across the passage; a detecting part for detecting a specimen present in the separation passage; and a specimen-injection monitor mechanism provided with CCD for detecting a specimen at a site where a specimen is injected into the specimen-injection-passage, the specimen-injection monitor mechanism being installed separately from the detecting part, wherein the specimen-injection monitor mechanism detects a specimen distribution along the specimen-injection-passage including at least the intersection between the specimen-injection-passage and the separation-passage, wherein the detecting part comprises a fluorescent-light detecting device for detecting a fluorescent light in a detection range, the fluorescent-light detecting device comprising: a first optical system for focusing, for image formation, a light from the detecting range into a slit hole; and a second optical system provided with a reflection-type diffraction grating, for separating a light from the slit hole and focusing the light, for image formation, onto a detecting element, wherein the specimen-injection monitor mechanism and the detecting mechanism are each provided with a fluorescent-light detecting optical system, which shares a common excitation light source in use.
