ABSTRACT:
A method and apparatus for selectively sorting individual particles, such as blood cells of a particular type of interest, from a plurality of particles of different types. Particles of interest are individually differentiated from other particles in a known manner, and a discrete control signal is produced in response to having identified a particle of interest. An impulse generator, acting in response to such control signal, applies a focused impulsive force on the identified particle of interest, such force serving to eject such particle from the plurality of particles of which it is a part. The ejected particles of interested are then collected in a separate container. The apparatus of the invention is preferably embodied in a flow cytometric instrument.
