Abstract: A particle analyzer in which tagged particles to be analyzed are drawn through a suspended capillary tube where a predetermined volume in the capillary tube is illuminated. The illumination scattered by said particles is detected by a detector to count all particles. The fluorescent illumination emitted by tagged particles is detected and the output signals from the fluorescent detectors and scatter detector are processed to provide an analysis of the particles.

Abstract: A method and apparatus for detecting a fluorescent substance tagged to a microparticle are described. The device comprises a single capillary flow carrier system for transporting the microparticle past a selected location, a source of electromagnetic radiation for irradiating the substance tagged to the microparticle, and a detection system for measuring fluorescent light emitted from the substance at the selected location. The method comprises transporting the microparticle to a selected location, irradiating a fluorescent substance tagged to the microparticle, and measuring the fluorescent light emitted from the fluorescent substance at the selected location.
