A flow-type field-flow fractionation apparatus 1 includes a first heater 14 and a second heater 16. The first heater 14 heats a carrier fluid between a first pump 12 and a separation cell 3. The second heater 16 heats a focus fluid between a second pump 15 and the separation cell 3. Thus, the carrier fluid heated by the first heater 14 is sent by the first pump 12 and flows into the separation cell 3, and the focus fluid heated by the second heater 16 is sent by the second pump 15 and flows into the separation cell 3. This can stabilize temperatures of the carrier fluid and the focus fluid flowing into the separation cell 3. Then, when an analysis is performed using the flow-type field-flow fractionation apparatus 1, the analysis can be performed with high reproducibility.
