Sample analysis methods and apparatuses and dynamic valve operation methods

A sample analysis method comprising:

• rotating a microfluidic apparatus at a first rotation speed to perform sample processing, the microfluidic apparatus comprising a chamber having 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 responsive to energy supplied from a valve driver;
• synchronizing and rotating the valve driver, which supplies the energy to the valve, and the microfluidic apparatus at a second rotation speed when the valve driver is aligned with the valve;
• and
• supplying the energy to the valve using the valve driver so as to operate the valve.

A dynamic valve operation method comprising:

• (a) rotating a microfluidic apparatus, the microfluidic apparatus comprising a chamber having a space for accommodating a fluid;
• a channel that provides a path through which the fluid flows;
• and a valve that selectively opens and closes the channel responsive to energy supplied from a valve driver;
• (b) rotating the valve driver, which supplies the energy to the valve, and the microfluidic apparatus at a second rotation speed when the valve driver is aligned with the valve;
• and
• (c) supplying the energy to the valve using the valve driver so as to operate the valve.
