Particle Size - sympatec

In most applications more than one particle is observed. As each individual particle may have its own particle size, methods for data reduction have been introduced - the particle size distribution, a fit to a specific model distribution and moments or an average particle size are used.

Particle Size Analytical Instruments

At the simplest level, information on particle size can help maintain a more consistent product, enhancing end-user value and profitability. At a more complex level, careful control of particle size can reduce the need for in-process modifications and reworking, so making products more competitive.

Particle Sizing - An Introduction

This is the difference between particle counting and particle sizing. Counting enables each particle to be recorded and counted. Since size is less important, a limited number of size classes are required. With sizing, the absolute number of particles is less relevant than the sizes or size distribution of particles and more size bands are needed.
