Laser Particle Size Analyzer Principle

Over the last twenty years laser diffraction has to a large extent replaced traditional methods of particle size analysis such as sieving and sedimentation a previously common practice for granular material.

Laser particle size analyzer principle.

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. 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 part of particle science and its determination is carried out generally in particle technology. Laser particle size analyzer principle.

View the malvern panalytical mastersizer here. 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. Particle size analysis is used to characterise the size of particles in a given sample. Every analyzer from the very first commercial prototype to the state of the art la 960 utilizes this principle.

Recognised for its capacity to reproduce results and size range spanning five. The light scattered by the particles at various angles is measured by a multi element detector and numerical values relating to the. This process does not depend on volumetric flow rate the amount of particles that passes through a surface over time. The ls 13 320 offers the highest resolution reproducibility and unsurpassed accuracy.

Ls 13 320 particle size analyzer. Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles as illustrated below. The role of laser diffraction in particle analysis. The basic workflow of a laser diffraction particle size analysis breaks down.

The ls 13 320 series is the most versatile and sophisticated laser diffraction particle sizing analyzer available today. 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.
