Abstract

The electrophoresis apparatus includes plural capillaries for separating fluorephore-labeled samples by electrophoresis, fluorescence detecting parts provided in a part of these capillaries arranged in the same place for detecting a fluorescence emitted by fluorephore labels when a part of the plural capillaries is scanned and irradiated by a laser beam, and a fluorescence detection system for detecting this fluorescence. The fluorescence detecting parts are scanned and repeatedly irradiated by the laser bean where a scanning period of the fluorescence detecting parts by the laser bean is t , and the fluorescence is detected by the fluorescence detecting system where an acquisition time of fluorescence signal is t (t ≦t ). The laser bean from a laser source is narrowly converged by a light collecting lens, and a galvanomirror is rotated in a rotation directional of the galvanomirror around the rotation axis of the galvanomirror so as to repeatedly scan the fluorescence detecting parts.
