Claim:
1. A sample analysis apparatus comprising: a first unit that rotates a microfluidic apparatus comprising a chamber with a space for accommodating a sample; a channel that provides a path through which the sample flows; and a valve that selectively opens and closes the channel; a valve driver that supplies energy, used to operate the valve, to the valve in a state of being separated from the microfluidic apparatus; a second unit configured to move the valve driver in a radial direction of the microfluidic apparatus; a third unit configured to rotate the valve driver with respect to a common rotation axis with a rotation axis of the microfluidic apparatus, the third unit comprising: a rotary member that is rotatable with respect to the common rotation axis, and on which the valve driver is provided so as to be configured to move in the radial direction by the second unit and a motor that rotates the rotary member; and a control unit configured to control the first and third units and the valve driver to supply energy to the valve while the microfluidic apparatus and the valve driver are being rotated at the same rotation speed, wherein the control unit is configured to control the first, second, and third units so that positions in the radial direction and angular positions of the valve driver and the valve are aligned with each other.
