The ls 13 320 series is the most versatile and sophisticated laser diffraction particle sizing analyzer available today.
Laser particle size analyzer principle.
The basic workflow of a laser diffraction particle size analysis breaks down.
The light scattered by the particles at various angles is measured by a multi element detector and numerical values relating to the.
Laser particle size analyzer principle.
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.
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.
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.
Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles as illustrated below.
Every analyzer from the very first commercial prototype to the state of the art la 960 utilizes this 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.
Particle size analysis is part of particle science and its determination is carried out generally in particle technology.
Recognised for its capacity to reproduce results and size range spanning five.
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.
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.
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.
The role of laser diffraction in particle analysis.
