  • 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.

If the function has 3 free parameters, for example, such as the mean, standard deviation, σ,and peak value or modulus of the distribution, then three moments will be needed to describe the distribution. The most common particle size distribution is called the log

    Particle Size Distribution OverviewMeasuring Particle Size DistributionWhy Measure PSD?ReferencesThe particle-size distribution (PSD) of a substance such as a powder, granular material, or particles in a solution, consisting of values or a mathematical function (see graphs below) that defines the relative amount, typically by mass or by length of all of the particles in the sample according to their individual sizes. In practice, there are very large variations in particle sizes and distributions within a very broad range of physical and chemical properties and morphological properties of particles. Such variations ar
