Flow-type field-flow fractionation apparatus

A flow-type field-flow fractionation apparatus comprising:

• a separation cell provided inside with a flow passage for a fluid, the cell having a carrier inflow port allowing a carrier fluid to flow into the flow passage, a focus inflow port allowing a focus fluid to flow into the flow passage, an outflow port allowing the carrier fluid that has passed through the flow passage to flow out, and a plurality of openings allowing a part of the carrier fluid to discharge to outside as a cross flow;
• at least one pump configured to send the carrier fluid and the focus fluid to the separation cell;
• a first heater configured to heat the carrier fluid and/or the focus fluid between the at least one pump and the separation cell, the first heater having a first set temperature;
• and
• an oven that houses the separation cell inside the oven, the oven configured to function as a second heater different from the first heater to heat the separation cell, the oven having a second set temperature, the oven having an inner area to accommodate the first heater therein,
• wherein the first and second set temperatures are the same with each other.
