  • Method and apparatus for detecting microparticles in fluid samples
    Patent number: 6816257
    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.
    Type: Grant

  • Method for measuring the volume of cells or particles
    Publication number: 20040090613
    Abstract: A method of determining the volume of cells or particles is described. The method relies upon the displacement of the liquid in a liquid suspension of cells or particles. The liquid suspension is strongly fluorescent and the volume of the cells or particles is measured by measuring the reduction of fluorescent light due to the presence of cells or particles.

  • Particle or cell analyzer and method
    Publication number: 20040005635
    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.
