Laser Diffraction (LD): Particle Size Analyzers :: Microtrac

Laser diffraction (LD) analysis, also known as static light scattering, is the most common method for the determination of particle size distributions other than traditional sieve analysis. The method is based on the deflection of a laser beam by an ensemble of particles dispersed in either a liquid or an air stream.
