Abstract
This invention measures the properties of individual particles in particle-suspended liquid by an optical technique or the like, causes the particle-suspended liquid to fall while separating the liquid into droplets containing the individual particles therein, and causes liquid droplets discharged from a nozzle to collide with the droplets from a direction differing from the direction of fall, in conformity with the properties of the particles discriminated by the measurement, so as to change the direction of fall of the falling droplets, thereby fractionating the particles.
