• Particle Size Result Interpretation Number vs. Volume

Interpreting results of a particle size measurement requires an understanding of which technique was used and the basis of the calculations. Each technique generates a different result since each measures different physical properties of the sample. Once the physical property is measured a calculation of some type generates a representation of a particle size distribution. The particle-size distribution (PSD) of a powder or granular material or particles dispersed in fluid is a list of values or a mathematical function that defines the relative amount typically by mass of particles present according to size. 1 PSD is also known as grain size distribution
