APPLICATION NOTE Basic principles of particle size analysis What is a Particle? PARTICLE SHAPE This may seem a fairly stupid question to ask! However, it is fundamental in order to PARTICLE SIZE understand the results which come from various particle size analysis techniques. Dispersion processes and the shape of materials makes particle size analysis a more complex matter than it first appears. The Particle size ...

a l u e If ambition & value goes together Application note 2017.02 Number and volume distributions in particle size analysis Particle size data are often expressed as volume or number distributions. These distributions express the percentage that each size class occupies of the overall distribution, either when calculated as a percentage of the total volume of particles or number of particles. In ...

APPLICATION NOTE Rapid Laboratory Particle Size Analysis of Cements Using Laser Diffraction David Pugh, Zhibin Guo, Tim Pang Application Research Lab, Bettersize Instruments Ltd. Abstract The laser diffraction method for measuring particle size was first invented commercially in 1974 and the first industries to use the technique were coal, ceramics, chocolate and cement. The particle size distribution or fineness of cement has been measured by ...
Assessing the Precision and Accuracy of Particle- Size Analysis with a Laboratory Laser-Diffraction Analyzer Katherine Norton, Physical Science Technician, U.S. Geological Survey Cascades Volcano Observatory, Vancouver, Wash., knorton@usgs.gov Introduction The purpose of this study is to assess the precision and accuracy of laboratory laser-diffraction particle-size distribution (PSD) analysis in support of an effort to formally adopt the method for routine use in U ...
