The primary choice is between wet or dry dispersion, but before choosing either it is .The world’s first laser diffraction particle size analyzer – the first-ever PSA – was invented in 1967. Key features. Compact 2-in-1 design to measure both wet and dry samples. . The size distribution of dry powders is often difficult to measure because the particles tend to agglomerate, which falsifies the results. .
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 .Particle size and particle size distribution with laser diffraction for lab applications ranging from below 0.1 µm to 8,750 µm .
