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 memberis provided along an inner peripheral surface of the rotor, has therein a channelfor a liquid sample by laminating a plurality of layers, and has an inlet for the liquid sample to the channeland an outlet for the liquid sample from the channel. By rotating the rotor, particles in the liquid sample in the channelare classified by centrifugal force. A restriction spacerrestricts the channelfrom being compressed to a height less than a certain height when the channel memberis compressed and deformed in a laminating direction.
