  • Patent number: RE35868
    Abstract: An apparatus for imaging and analyzing particle components in a sample liquid flow containing particle components such as blood and urine, or fine particles of organic high polymer in suspension or the like. A conventional particle imaging flow cytometer is combined with a light source such as a lamp with small coherence, and an image intensifier with gate function of high response, so that a clear particle image without a deflection or interference fringe is obtained. Thus, in the apparatus having the still imaging function, by using the image intensifier with a high speed gate function, even with a light source of a long luminous time such as a lamp, a clear still image of a particle flowing at high speed is obtained.
