Particle Measurement: Particle Size Analyzers :: Microtrac

The result of this particle measurement is in any case: the two objects are different in size. Sieve analysis shows that both objects fit through a sieve with 16 mm aperture, while they are retained by a sieve with a mesh size of 14 mm. Sieve analysis thus characterizes both particles as the same size: they have the same equivalent diameter ...

Dynamic Light Scattering Particle Size Distribution Analysis

Particle size can be determined by measuring the random changes in the intensity of light scattered from a suspension or solution. This technique is commonly known as dynamic light scattering (DLS). In general, the technique is best used for submicron particles and can be used to measure particle with sizes less than a nanometer.
