Abstract
A capillary array includes N analysis capillaries filled with a separation medium having a refractive index of nand used for electrophoretic analysis and N±1 lens capillaries filled with a medium having a refractive index of n4 and not used for the electrophoretic analysis, in which the N analysis capillaries and the N±1 lens capillaries are alternately arranged on the same array plane. When an outer diameter is defined as 2R, an inner diameter is defined as 2r, a refractive index of a medium of an outside is n, and a refractive index of a material is defined as nfor each of the N analysis capillaries and the N±1 lens capillaries, and when a refractive index ntakes any value within the range of 1.33≤n≤1.42, R, r, n, n, n, and nsatisfy a predetermined relationship, whereby the N analysis capillaries are efficiently simultaneously irradiated with the laser beam incident from a side of the array plane.
