Laser diffraction particle size analyzer working principle.

The larger the particle the smaller the angle and the higher the intensity of the scattering. At its very most basic laser diffraction is about the relationship between particle size and the angle and intensity of scattered light. Hundreds of refinements to the basic design have been included to improve performance and usability. Laser diffraction has become one of the most commonly used particle sizing methods especially for particles in the range of 0 5 to 1000 microns.

The ls 13 320 series is the most versatile and sophisticated laser diffraction particle sizing analyzer available today. 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. Particle sizing by laser diffraction. Light scatters more intensely and at smaller angles off of large particles than small particles.

The principle of laser diffraction is the relationship that exists between light scattering its angle and intensity and particle size. 80 photodetectors covering an approximate angular range of 0 170 degrees. The smaller the particle size the larger the angle of light scattering. 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.

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. Ls 13 320 particle size analyzer. Two light sources at different wavelengths. A guide to understanding laser diffraction principles theory.

Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles as illustrated below. A typical laser diffraction optical system will include. As a technique that measures particle size distribution for both wet and dry dispersions it offers many advantages including a high level of precision fast response. The ls 13 320 offers the highest resolution reproducibility and unsurpassed accuracy.

Every analyzer from the very first commercial prototype to the state of the art la 960 utilizes this principle.
