Abstract
Provided is a field-flow-fractionation apparatus that is configured to supply a carrier fluid to a waste fluid chamber through a fluid supply flow path at a flow rate higher than a set flow rate of a flow rate adjusting part at a timing between an end of analysis of a sample and a start of analysis of a subsequent sample, thereby forming a flow of the carrier fluid from the waste fluid chamber to the separation channel. Accordingly, the sample adhering to a separation membrane is separated from the separation membrane and is discharged from the outlet port.
