Abstract
A flow-type field-flow fractionation apparatusincludes a first heaterand a second heater. The first heaterheats a carrier fluid between a first pumpand a separation cell. The second heaterheats a focus fluid between a second pumpand the separation cell. Thus, the carrier fluid heated by the first heateris sent by the first pumpand flows into the separation cell, and the focus fluid heated by the second heateris sent by the second pumpand flows into the separation cell. This can stabilize temperatures of the carrier fluid and the focus fluid flowing into the separation cell. Then, when an analysis is performed using the flow-type field-flow fractionation apparatus, the analysis can be performed with high reproducibility.
