Field flow fractionation device

Abstract

In field flow fractionation, this refers to separating multiple types of particles that exhibit different behaviors in response to a magnetic field. [Solution] The field flow fractionation apparatus in this disclosure classifies particles contained in a sample. The field flow fractionation apparatus comprises a flow cell, a fluid supply unit, a sample introduction unit, and a magnetic field generation unit. The flow cell constitutes a channel through which particles flow. The fluid supply unit supplies fluid to the channel. The sample introduction unit supplies a sample to the channel. The magnetic field generation unit generates a magnetic field acting on the channel.
