Laser Particle Size Analyzer Principle

Particle size analysis is part of particle science and its determination is carried out generally in particle technology.

Laser particle size analyzer principle.

The role of laser diffraction in particle analysis. Particle size analysis particle size measurement or simply particle sizing is the collective name of the technical procedures or laboratory techniques which determines the size range and or the average or mean size of the particles in a powder or liquid sample. Recognised for its capacity to reproduce results and size range spanning five. The basic workflow of a laser diffraction particle size analysis breaks down.

Laser diffraction measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample. Laser diffraction analysis also known as laser diffraction spectroscopy is a technology that utilizes diffraction patterns of a laser beam passed through any object ranging from nanometers to millimeters in size to quickly measure geometrical dimensions of a particle. The ls 13 320 series is the most versatile and sophisticated laser diffraction particle sizing analyzer available today. In fact the analyzer itself does not measure particle size it measures the angle and intensity of light scattered from the particles in your sample.

The ls 13 320 offers the highest resolution reproducibility and unsurpassed accuracy. It works on the principle that when a beam of light a laser is scattered by a group of particles the angle of light scattering is inversely proportional to particle size ie. Particle size analysis is used to characterise the size of particles in a given sample. View the malvern panalytical mastersizer here.

A representative sample dispersed at an adequate concentration in a suitable liquid or gas is passed through the beam of a monochromatic light source usually a laser. Malvern panalytical s unique practical laser diffraction particle size analysis know how enables the mastersizer to deliver results you can rely on with data quality analysis that empowers both particle sizing experts and measurement novices to deliver insight and results you can trust. Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles as illustrated below. Laser particle size analyzer principle.
