Laser diffraction particle size analyzer Mastersizer 3000 (laser granulometer) - a versatile tool for the rapid and accurate particle size analysis (measurement of particle size distribution), suspensions, emulsions or dry powder materials. A wide range of overlapping dimensions from millimeters to nanometers, exceptional performance and reliable measurement results do not depend on the operator - all in an extremely compact package.


Mastersizer 3000 to determine the particle size ( granulometry ) uses a laser diffraction method . The method is based on measuring the intensity of scattered light , the passage of the laser beam through the dispersed sample ( suspension, emulsion , dry powder ) . These scattered light is analyzed and the particle size distribution is computed ( reconstructed ) based on the measured angular dependence of the light scattered by particles dispersed sample.
