In granulometry, 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. [1] Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size .
The Mastersizer 3000+ Pro is a mid tier system for particle size analysis by laser diffraction when you do not need the widest size range. This system offers robust size measurements from 0.1 to 2500 microns and benefits from a more advanced software experience with Mastersizer Xplorer and automated dispersion options.
Developing an appropriate method for measuring particle size distribution using laser diffraction requires a structured approach. Samples analyzed as a dry powder have a few unique considerations compared to wet analysis, but the majority of the content in this document will be applicable to all methods. In all cases the basic goals remain the In laser diffraction particle size analysis, inaccurate results can be caused by particle agglomerating in the suspension, especially when they are fine.Therefore, a full dispersion of the sample prior to measurement is essential. Three effective methods are available for the sample dispersion when using the wet method. Primary dispersion of aggregates can .
