  • Method and apparatus for discriminating minute particles
    Patent number: 4778593
    Abstract: In order to discriminate minute particles such as biological particles or organic polymers, a suspension of minute particles is formed into a particle stream with the individual particles substantially separated from each other, the particle stream is irradiated with a high-intensity light beam, the particle stream irradiated with the high-intensity light beam is formed into droplets, and the particle in each droplet is discriminated in accordance with the intensity of light emited from the particle upon irradiation with the high-intensity light beam. In discriminating the particles, a high-intensity light pulse is used as the high-intensity light beam, and each minute particle is discriminated in accordance with a change in the emitted light intensity over a period of time.
