Dynamic Light Scattering - Sympatec

Dynamic light scattering (DLS) is a robust, simple and non-contact method for the measurement of particle size and particle size distributions from the nanometre to the submicron range. With high sensitivity it is ideally suited for detection of size changes even as a function of time. Process modifications occurring in seconds may be traced in real time. Within a measuring time of just a few

A Comparison of the Particle Sizing Techniques of Sieve

method used to characterise particle size distributions and is employed throughout a number of industries. There are 2 types of sieve analysis that can be carried out; wet sieving and dry sieving. Wet sieving is suitable for particle sizes from 20μm up to 3mm while dry sieving is suitable for particles from 30μm up to 125mm.

ASTM D422 - Standard Test Method for Particle

scope: This test method covers the quantitative determination of the distribution of particle sizes in soils. The distribution of particle sizes larger than 75 μm (retained on the No. 200 sieve) is determined by sieving, while the distribution of particle sizes smaller than 75 μm is determined by a sedimentation process, using a hydrometer to secure the necessary data (Note 1 and Note 2).

Measuring API Particle Size Distribution |

One method that I have used to directly estimate/measure the particle size of API particles in tablets, which would also work for blends and granulations, is mapping. By picking a peak unique to the API, a visual distribution of the API can be obtained. In order to get a particle size distribution, you would need to extend the analysis by counting the dimensions for a relevant number of

Particle-size distribution - Wikipedia

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. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

Particle Size Analysis for Soil and Sediment |

Particle size analysis is the measurement of the proportions of primary solid particles from soil and sediment. The various particle sizes are determined either by their capacity to pass through different mesh sieves or by their rates of settling in water. The proportions are usually represented by the relative weights of particles within the stated classes.
