Abstract:
1. A device comprising: a multi-capillary array including a plurality of capillaries that are filled with a separation medium, each capillary of the plurality having a respective first portion into which a sample can be introduced, and a respective light-irradiatable portion that is capable of being irradiated with excitation light, wherein the light-irradiatable portions are arranged in a row on a plane; a power supply capable of supplying a voltage to a current path that includes the first portions and the light-irradiatable portions; an excitation light source capable of emitting excitation light along a path in a direction toward the plurality of light-irradiatable portions simultaneously; a detector capable of detecting light emitted by samples in the light-irradiatable portions upon irradiation with excitation light; a sealed vessel that retains a substance having a refractive index larger than that of air but smaller than that of water in areas between two or more adjacent light-irradiatable portions and a bubble, wherein the multi-capillary array includes a bubble-accommodating space that is capable of accommodating the gas, and the bubble-accommodating space is provided in a position through which excitation light, emitted from the excitation light source, does not pass; and a bubble eliminating block for preventing the bubble from entering the path of excitation light.
