Laser Particle Size Analyzer (Laser Diffraction)

Laser diffraction particle size analyzers are used to measure the sizes of particles in a material. Particle size is calculated by measuring the angle of light scattered by the particles as they pass through a laser beam. Laser diffraction analyzers are used in many applications, including manufacturing, quality control and product development. Because this technique can continuously measure particle sizes across a wide range, from 10 nm to 3 mm, laser diffraction particle size analyzers are often used in industrial settings.

A laser diffraction particle size analyzer uses multiple light detectors, with more detector elements extending sensitivity and size limits. The time needed to measure particle sizes varies by instrument, ranging from 2 seconds to 10 minutes per sample. The light source used by a laser particle size analyzer also affects particle size measuring limits; shorter wavelength violet and UV lasers are better suited to measure submicron-sized particles than red lasers.
