Particle/fiber size analysis is the combined name of the laboratory techniques which determines the size range, and/or the average, or mean size of the particles/fibers in a powder or liquid sample.
The particle size measurement is typically achieved by means of devices called Particle Size Analyzers which are based on different technologies, such as high definition image processing, analysis of Brownian motion, gravitational settling of the particle and light scattering of the particles.
Within particulate samples the most important physical property is particle size. The Measurement of particle size distributions is routinely carried out across a wide range of industries and is often a critical parameter. The particle size can have considerable importance in a number of industries including the chemical, food, mining, forestry, agriculture, nutrition, pharmaceutical, energy, water and aggregate industries.
At BEAM we offer the analysis of particle size distributions from sub-nanometer to millimeters.
Challenge
The size of a particle influences the method used for its measurement; thus it is important to know the size range one is working with or communicate that to the technician beforehand. That will prevent data being misinterpreted.
