PROBLEM TO BE SOLVED: To resolve a difference in a capillary length to simplify an analysis method by holding respective equal-length capillaries having fixed both ends and deformed in arch shapes, in a non-contact state with a member provided with cutouts. SOLUTION: A fluorescence-labeled sample of DNA fragments supplied from each sample injection part 2 is fed into each capillary 3 for electrophoretic separation together with an electrolytic solution, and then, electrophoresis is performed with a negative electrode bath kept zero voltage and with a positive electrode bath optical cell 1 kept a positive voltage. A sheath liquid 9 is supplied from a sheath liquid vessel 4 to separated and flowed-out components according to masses in the fluorescence- labeled samples such that each the flowed-out component has a sheath flow state. A flowed-out position is irradiated with exciting light from an exciting light source 5, while a light detection means 6 detects the flowed-out fluorescence labels to output light data to a data analysis means 7. The data analysis means 7 analyzes the light data to decide a base array of the DNA. At that time, the equal-length capillaries 3 having constrained both ends and deformed in arch shapes are inserted in respective cutouts of a hold member one by one so as to be held in a mutual non-contact state. |
