PARTICLE size is an important attribute in APIs, solid oral drug products (tablets and capsules – impacting on homogeneity, flow and processing), and as a critical quality attribute in semisolids (suspensions) and sterile liquid products (injectables). Particle size analysis has become a proxy for routine surface area measurement.
But what is the particle size distribution and ISO code for the cube of silicon in the oil? Assuming the oil is totally clean, we now have one 60 x 60 x 60 µg cube in 1 ml of oil, so the number of particles in the oil is one. Obviously, having only one particle in an oil sample is unrealistic.
PARTICLESIZE DISTRIBUTION ESTIMATION BY ANALYTICAL SIEVING Sieving is one of the oldest methods of classifying powders and granules by particlesize distribution. When using a woven sieve cloth, the sieving will essentially sort the particles by their intermediate size dimension (, breadth or width). Mechanical sieving is most ...

In general, the method used to determine particle size dictates the type of equivalent diameter that is measured. This is explained for each particle size analysis method described later in this chapter.
The CAMSIZER P4 particle analyzer has been developed to comprehensively characterize dry, free flowing bulk materials. Whereas traditional sieve analysis, for example, can only determine the approximate particle size, the CAMSIZER P4 simultaneously measures both particle size and shape – with much more detail and at a higher resolution.
Clay is any soil particle below millimeters, including colloidal clay so small it does not settle out of suspension in water. Mechanical Analysis of Soil Mechanical Analysis of Soil Mechanical Analysis of Soil The percentage distribution of those parts determines soil structure. Mechanical analysis is the determination of the size range

Particle size plays a critical role in the formulation of a drug product especially for solid oral dosage forms. It can impact the product stability, dissolution profile, efficacy, and ultimately, bioavailability.
The Importance of Particle Size and Particle Size Distribution. The particle size and particle size distribution (PSD) of these materials are of great importance to the end user because they affect key properties such as rheology, film gloss, surface area and packing density.

particle size of ground cereal grains incorporated into animal diets. Additionally, the uniformity of particle size distributions has been suggested as having an important role in animal nutrition. Although measuring particle size and distribution remains an important aspect in quality control, a lack of communication between academia
Elzone Particle Size Analyzer Technique Overview. The Elzone uses the electrical sensing zone method (Coulter principle) of particle measurement. One advantageous characteristicof this measurement technique that differentiates it from the laser light scattering method is that Elzone data are unaffected by samples that have mixed optical properties,colors, and shapes.
