Understanding Particle Size Distribution Calculations - HORIBA

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.

Sieve analysis - Wikipedia

Sieve analysis has, in general, been used for decades to monitor material quality based on particle size. For coarse material, sizes that range down to #100 mesh (150μm), a sieve analysis and particle size distribution is accurate and consistent. However, for material that is finer than 100 mesh, dry sieving can be significantly less accurate.

relationship between molecular weight and particle size was to identify the sources of molecular weight poly-dispersity and thus to provide better predictions of the molecular weight distribution. The second purpose was to obtain ad­ ditional insight into the mechanism of emulsion polymeri­ zation so that a more accurate model may be obtained.
