This is called particle size analysis or particle sizing in most cases particle distribution will be displayed in the classic bell curve which demonstrates the smallest average and largest particles when searching for particle size distribution numbers youll often come across the term d50
Particle size distribution analyses are just one of the many services offereda particle size distribution analysis psd is a measurement designed to determine and report information about the
With laser diffraction the particle size distribution is determined by the characteristic diffraction pattern of a particle collective in contrast image analysis captures the physical properties of each single particle the distribution of a property such as size or shape descriptor can thus be resolved in
