  • MEASUREMENT OF PARTICLE SIZE DISTRIBUTION
    Publication number: 20030030802
    Abstract: A particle size distribution analysis apparatus comprising a sample measurement zone adapted to define a sample of particles, a light emitting means adapted to provide a source of light incident upon the sample measurement zone, and at least a first detection means adapted to measure light levels in the apparatus at particular scattering angles and output a signal to a computation means enabling the particle size distribution of particles contained within the sample to be determined, wherein the computation means is adapted, in use, to calculate a particle size distribution taking into account reflections by the measurement zone of light scattered off the particles

  • Sample handling system
    Publication number: 20020054834
    Abstract: A particle suspension handling system comprises a dispersion unit, a transport element, a cell and an outlet region. The dispersion unit has a transducer externally thereof, which is arranged, in use, to transfer energy into the suspension. The transport element is located within the dispersion unit. The transport element is arranged, in use, to recirculate the suspension about a flow path including the dispersion unit and the cell. The outlet region includes first and second valve members. The valve members can be arranged in a first configuration wherein they are spaced apart such that the space between them defines a discharge opening via which a fluid or the suspension exits the system, in use. The valve members can also be arranged in a second configuration wherein they abut and a flow path of substantially constant cross-section is provided about the outlet region.

  • Relating to the measurement of particle size distribution
    Patent number: 6177994
    Abstract: A particle size distribution analysis apparatus wherein there are provided a sample measurement zone adapted to contain a sample of particles, a light emitting means adapted to provide a source of light incident upon the measurement zone, and a detection means adapted to measure light levels at different scattering angles and to output signals to a computation means, enabling the size of particles contained within the sample to be determined, wherein the light emitting means comprises a first light source emitting a substantially monochromatic first wavelength of light and a second light source emitting a substantially monochromatic second, different, wavelength of light.
