Laser Diffractometry
Laser Diffractometry (Laser Diffraction) Laser Diffractometry is an optical technique that uses diffraction patterns for particle size analysis of suspensions, colloidal dispersions, dry powders and aerosols. The scattering of an incident laser beam, by particles dispersed in a suitable medium, yields characteristic interference patterns that depend on the size of the particles involved. The intensity of scattered light varies in direct proportion to the particle size. The scattering angle, however, varies inversely with particle size. A Laser Diffractometry measurement is performed by passing a laser beam of specified wavelength through a dispersed particulate sample. The angular variation in intensity of the scattered light is measured, using detector arrays placed at various angles. The intensity and angular patterns are then analyzed, to calculate the size of the particles in accordance with the theoretical frameworks of Mie or Fraunhofer scattering. Particles that are much larger than the incident wavelength display Fraunhofer scattering, while Mie scattering is observed for particle sizes comparable with laser beam wavelength.
