[Particle Size] Particle Size Analysis by Light Diffraction Principle, Method and Calibration

The laser light diffraction technique used for the determination of particle size distribution is based on the analysis of the diffraction pattern produced when particles are exposed to a beam of monochromatic light. Historically, the early laser diffraction instruments only used scattering at small angles. However, the technique has since been broadened to include laser light scattering in a wider angular range and application of the Mie theory, in addition to the Fraunhofer approximation and anomalous diffraction.

[Particle Size] Principles and Methods of Geological Particle Size Analysis

Particle size is a fundamental property of sedimentary materials that may tell us much about their origins and history. In particular the dynamical conditions of transport and deposition of the constituent particles of rocks is usually inferred from their size. The size distribution is also an essential property for assessing the likely behaviour of granular material under applied fluid or gravitational forces, and gauging the economic utility of bulk materials ranging from foundry sands to china clay.

[Particle Size] Particle Size Characterization Techniques & Principles Listings

Particle size characterization can be done using various commercially available instruments. Different instruments are based on different techniques, sometimes even a combination of techniques. Mainly includes Laser Diffraction Technique, Dynamic Light Scattering (DLS), Automated Imaging, Electron Stream Sensing Zone Technique (Coulter Counter Method) and X-Ray Sedimentation.

[Particle Size] Three Key Measurement Methods for Particle Size

There is a wide range of measurement methods for particle sizing, each of which has capability over a certain range of particle size. The three principal methods that have been studied are the following: Laser diffraction, Sedimentation of a suspension and Electrozone sensing.
