Hoe het werkt

Hoe het werkt

The Mastersizer 3000 uses the technique of laser diffraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.

A typical system is made up of three main elements:

  • Optical bench - A dispersed sample passes though the measurement area of the optical bench, where a laser beam illuminates the particles. A series of detectors then accurately measure the intensity of light scattered by the particles within the sample for both red and blue light wavelengths and over a wide range of angles.
  • Sample dispersion units (accessories). Sample dispersion is controlled by a range of wet and dry dispersion units. These ensure the particles are delivered to the measurement area of the optical bench at the correct concentration and in a suitable, stable state of dispersion.
  • Instrument software. The Mastersizer 3000 software controls the system during the measurement process and analyzes the scattering data to calculate a particle size distribution. It also provides both instant feedback during method development and expert advice on the quality of the results.
