The text that follows is a discussion of the theory and application of a laser light scattering approach to particle size measurement. Particular emphasis will be placed on examples of presently-operating wet and dry monitor systems. Advantages of this measurement technique will be stressed, particularly the capability of both wet and dry .the processes themselves. A major information in this context is the particle size distribution (PSD). While early methods such as sieve analysis and sedimentation required a time consuming laboratory operation, modern methods allow for an instantaneous monitoring of particle size and shape of the production directly in the process environment.

The LA-960 combines the most popular modern sizing technique with state of the art refinements to measure wet and dry samples measuring 10 nanometers to 5 millimeters. The central idea in laser diffraction is that a particle will scatter light at an angle determined by that particle’s size. Laser diffraction analysis is a fast, reliable and automated method that provides detailed and highly resolved soil and sediment particle size distribution. In recent studies, the methods were compared against independent methods based on direct observation of particles by digital imaging. The optimized Particle Size Distribution method is accurate, simple, repeatable and suitable for determination of . of laser diffraction particle size analyzers set the standard for delivering rapid, accurate particle size distributions for both wet and dry dispersions. From assessing product .
Referencing dry with wet results Pressure titration for a pharmaceutical powder. Comparison with a reference wet measurement shows that this material should be characterised at low pressures. ISO13320 (2009) notes that if dry dispersion is applied a “pressure/particle size” titration should, in the ideal case, identify a region where .

With modern laser diffraction particle size analyzers sampling is now the greatest potential source of error, especially when measuring large particles and/or when the specification is based on size parameters close to the extremes of the distribution. . 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.
