Abstract

A sample analysis substrate mountable and detachable to a sample analysis device and includes: a plate-shaped base substrate; and a chamber, the chamber being a space in which to cause a binding reaction, The sample analysis device includes: a motor to rotate the sample analysis substrate; a first magnet unit to attract the magnetic particles; a first actuator to move the first magnet unit to change relative positions of the first magnet unit and the sample analysis substrate; and a control circuit to control the motor, the drive circuit, and the first actuator. The first magnet unit shaped as a whole shape or a partial shape of a circle or a ring. During a B/F separation for separating reacted substance from unreacted substance, the first actuator moves the first magnet unit to a position where the magnetic particles in the chamber are attracted by the first magnet unit.
