Particle Size Distribution . Particle Sizing Metrics The most widely used method of describing particle size distributions are D values. The D10, D50 and D90 are commonly used to represent the midpoint and range of the particle sizes of a given sample.
dominate in particle size measurement variability. A simple table/check list is provided in Appendix 1 to assist personnel responsible for particle size measurement to quickly develop suitable protocols. A number of excellent readily available sources of information on particle size measurement .
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.
Particle Size Distribution D50 is also known as median diameter or medium value of particle size distribution, it is the value of the particle diameter at 50% in the cumulative distribution. Particle Size Distribution D50 is one of an important parameter characterizing particle size.
You can get a "normal" particle size distribution, by selecting particle size diameter in µm, i.e. d10, d50 and d90. This way of representing the result is very useful when microscopy is used supplementary to, for instance, a laser diffraction experiment.

Particle size, such as D50, is found by interpolation. The high and low of the range in which the percentile is found are used. For example if 45% of the particles are smaller than 2 mm and 60% of the particles are less than 4 mm then the size of D50 is in the range of 2 to 4 mm.
without changing the particle size distribution, others may be affect-ed by dilution, which makes mean-ingful particle size measurement challenging. Optical microscopy, however, is a technique which lends itself quite naturally to the determina-tion of particle size in situ. Particle …
of the distribution has a smaller particle size and ten percent has a larger particle size. The d10 diameter has ten percent smaller and ninety percent larger. A three point specification featuring the d10, d50, and d90 will be considered complete and appropriate for most particulate materials. How these points are expressed may vary.

The definition for D50 or Dv(50), then, is then the size point below which 50% of the material is contained, and the D10 or Dv(10) is that size below which 10% of the material is contained. This description has long been used in size distribution measurements by laser diffraction.
Particle size distributions can take on a large number of shapes and sizes. It would be impossible for a practical analyzer design to properly display all of these curves. For this reason, particle size distributions are represented by a series of segments or channels known collectively as a histogram.

Particle size distribution Stamylan ® UH contains less than 1% of particles measuring smaller than 63 microns. Typical particle size distribution, expressed in span (D90-D10)/D50 is 0.8, where other UHMWPE grades have a span greater than 1 as is shown in the figure.
Sieve analysis presents particle size information in the form of an S – curve of cumulative mass retained on each sieve versus the sieve mesh size. The most commonly used metrics when describing particle size distributions are D-Values (D10, D50 & D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass.
