Abstract: There is a phenomenon where a noise in a spike shape caused by, for example, impurities and a noise peak having a spectrum different from a wavelength spectrum of a labeled fluorescent substance are detected during a capillary electrophoresis. Therefore, the disclosure provides a technique to identify an intensity of the labeled fluorescent substance itself without an effect by a noise fluorescence peak caused by impurities. In the disclosure, a fluorescence intensity property (a fluorescence profile of a noise) common to the noise peaks is set, the noise peak is handled as a fluorescent substance different from the labeled fluorescent substance, and the fluorescent substance and the noise are separated by color converting with the labeled fluorescent substance+the noise fluorescent substance (see FIG. 5).

Abstract: A capillary electrophoresis apparatus is disclosed that does not discharge and achieves both compactness and performance even with a part configuration having insufficient spatial distance or creeping distance. This capillary electrophoresis apparatus is provided with a resistance heater for heating capillaries, an electrode holder that holds capillary electrodes and is connected to a high-voltage unit, and a conductive member that at least partially comprises metal and has been grounded to a low potential. The electrode holder and conductive member are in contact with heat-dissipating rubber disposed there between that composes a structure comprising an insulation member. As a result of this configuration, discharge risk is reduced through the reduction of the potential of parts near the high-voltage unit and the slow reduction of the high potential of the high-voltage unit.
