How it works
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.
