Particle Size Distribution Analysis

A Particle Size Distribution analysis (PSD) is a measurement designed to determine and report information about the size and range of a set of particles representative of a material. Particle size and distribution analysis of a sample can be performed using a variety of techniques, each with advantages and disadvantages, depending on the sample properties and question at hand.

Knowing and controlling the particle size distribution of the primary particles and/or agglomerates present in a material is of utmost importance for research, product development, processing, handling, packaging and quality control. The number of standard organizations and regulatory agencies who have current particle size distribution guidance documents and/or specification requirements is a clear indication of the importance of this information.
