  • Device for determining the characteristics of particles in suspension in a liquid
    Patent number: 5087823
    Abstract: A device for determining the characteristics of particles in suspension in a liquid, comprising a sampling device (2) for injecting samples of particles; a fractionator (3) for sorting those particles as a function of their length; an optical measurement cell (4) which receives the output of the fractionator, and a programmable controller (6) for calculating the values of the intensities and combinations of those values in the various directions of the optical radiation. The optical measurement cell includes a laser for transmitting polarized, coherent light through the particles in suspension and for collecting the light diffracted in various directions.
