ISO 14488, Particulate materials -- Sampling and sample splitting for the determination of particulate properties, available at webstore.ansi.org 3. ISO 13320, Particle size analysis -- Laser diffraction methods -- Part 1: General principles 4.The proven HELOS laser diffraction series offers a powerful technology for particle size analysis of powders, granules, suspensions, emulsions, sprays and other particulate systems from below 0.1 µm to 8,750 µm. 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 particle size is nearly constant over a range of pressures. This indicates that .

Developing an appropriate testing method for measuring particle size distribution in liquids using laser diffraction requires a structured approach. A number of parameters of the test method must be evaluated including sampling, solvent, refractive index, dispersion, system settings, and concentration. These parameters may have a significant effect on the reported results, so each .
particle size is reported as a volume equivalent sphere diameter. The Mastersizer 3000 uses the technique of laser diffraction to measure particle size distributions from 10nm up to 3.5mm. Wide dynamic range The patented folded optical design in the Mastersizer 3000 provides an impressive particle size range from 10nm up to 3.5mm using a single 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 . A wet analysis (observing the particles on a wet slide with particles in solutions) was also tested, but it was found that it was more difficult to obtain a proper dispersion of the samples. .
