Abstract
A field-flow fractionation device includes a separation channel, a carrier fluid supplier, a separation membrane, a waste liquid chamber, a cross-flow flow rate adjuster, and a carrier fluid adder. The carrier fluid adder is configured to add, to a flow of a carrier fluid having passed through the separation membrane, a flow of another carrier fluid at a carrier fluid adding position set on an upstream side of the cross-flow flow rate adjuster so that the flow rate of the carrier fluid flowing into the cross-flow flow rate adjuster is larger than the flow rate of the carrier fluid having passed through the separation membrane.
