Rapid, reliable particle size measurements made easy. The Mastersizer 3000 is the latest generation of the world’s most widespread particle sizing instrument, used by many thousands of companies and research institutes across a wide range of industries. Malvern Panalytical’s considerable experience and applications know- how has gone into every stage of the design of the Mastersizer 3000 instrument, from fundamental particle sizing performance right through to user ergonomics and method advice.

In a laser diffraction measurement a laser beam passes through a dispersed particulate sample and the angular variation in intensity of the scattered light is measured. Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles. 

The angular scattering intensity data is then analyzed to calculate the size of the particles that created the scattering pattern using the Mie theory of light scattering. The particle size is reported as a volume equivalent sphere diameter.

Measuring Mode

In a laser diffraction measurement a laser beam passes through a dispersed particulate sample and the angular variation in intensity of the scattered light is measured. The angular scattering intensity data is then analyzed to calculate the size of the particles that created the scattering pattern using the Fraunhofer or Mie theory of light scattering.
