Measuring device for the measurement of fluid flow rates
Fluorescence analysis of stained particles
Multidimensional slit-scan flow system
Apparatus and method for detecting platelets in whole blood Patent #: 4577964
AbstractA flow cytometry apparatus for determining one or more characteristics of particles or the like flowing in a liquid stream includes a nozzle for generating a liquid flow stream for moving particles therethrough substantially one at a time. A light source provides a beam of focused light to illuminate the particles moving in the stream. A beam steering member is positioned to adjust the focal point of the light beam on the particles by refracting the light beam to cause a displacement of the focal point. At least one detector is provided for detecting light and for associating that light with one or more characteristics of each particle.
