An electrophoresis device includes a mounted reference capillary and a focused optical system. A 2D image of light containing autofluorescence and a 2D image of Raman-scattered light are obtained from the separation medium, and pattern data for autofluorescence and Raman-scattered light are obtained from these. An electrophoresis capillary is mounted in the electrophoresis device, pattern data for autofluorescence and Raman-scattered light is obtained in the same way at each of multiple different focal positions of the optical system, and the focal position of the optical system that best matches that of the reference capillary is used as the in-focus position.

In a capillary electrophoresis device, detection window sections of a plurality of capillaries are arranged, and a capillary cassette is mounted and used, the capillary cassette having an excitation-side positioning part and a fluorescence-side positioning part so as to hold the detection window section array therebetween. The capillary electrophoresis device includes an excitation optical system unit and a fluorescence-receiving unit having positioning parts positioned to the capillary cassette. The excitation optical system unit includes a rod-like lens array configured to irradiate an excitation light to each detection window section. The fluorescence-receiving unit includes a rod-like lens array configured to receive a fluorescence from each detection window section, and an optical fiber for each rod-like lens configured to guide fluorescence from the rod-like lens to a detector side.

A microchip processing apparatus processes a microchip with at least one main separation channel. The microchip processing apparatus includes a holding part configured to hold the microchip, a container containing a sample or a reagent, and a dispensing probe having a needle formed on a tip of the dispensing probe. The dispensing probe is actuated to be inserted into the container from above the container, to draw the sample or reagent, and to inject to a prescribed position on the held microchip. A dispensing probe driving mechanism moves the dispensing probe between prescribed positions of the microchip and the container.
