Abstract
In an instrument configured to spectroscopically divide fluorescences emitted from a plurality of capillaries and collectively measure the fluorescences using an image sensor, when the number of pixels of a binning region on the image sensor on which a predetermined wavelength-band component of each fluorescence is projected is denoted by B, the number of pixels of hardware binning is denoted by B, the number of pixels of software binning is denoted by B, B=B×B, the total noise measured in a case where B=B=B=1 is denoted by N, the readout noise is denoted by N, the dark-current noise is denoted by N, and the shot noise is denoted by N, B, B, B, N, N, N, and Nsatisfy a predetermined relationship, thereby realizing high sensitivity and high dynamic range in fluorescence measurement.
