Understanding Interpreting Particle Size Distribution ...

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.

Guide To Determine Particle Size Distribution

Particle size distribution (PSD) is the means of measuring the number of particles by mass and size to calculate a size and mass range. D-values can be thought of as a mass division diameter. It is the diameter which, when all particles in a sample are arranged in order of ascending mass, divides the sample's mass into specified percentages.
