Abstract: A centrifugal field-flow fractionation device includes an annular rotor, an arc-shaped channel member, a rotation drive unit, and a restriction unit. A channel member 16 is provided along an inner peripheral surface of the rotor, has therein a channel 161 for a liquid sample by laminating a plurality of layers, and has an inlet for the liquid sample to the channel 161 and an outlet for the liquid sample from the channel 161. By rotating the rotor, particles in the liquid sample in the channel 161 are classified by centrifugal force. A restriction spacer 64 restricts the channel 161 from being compressed to a height less than a certain height when the channel member 16 is compressed and deformed in a laminating direction.

Abstract: A plurality of light-receiving elements that are arranged in two rows are provided on a light-receiving surface of a detector. A slit image formed on this detector. One group of a plurality of the light-receiving elements are arranged consecutively in a displacement direction of the slit image to form a row (one light-receiving elements row), and another group of a plurality of the light-receiving elements are also arranged consecutively in the displacement direction of the slit image to form a row (another light-receiving elements row). The one light-receiving elements row and the other light-receiving elements row are in contact with each other.
