WebJun 3, 2013 · Laser diffraction has been the most common particle size analysis technique for many years. The technique is fast, flexible, and easy to use for a wide variety of sample types. Knowledge of the sample and dispersing medium refractive index (RI) is often required to generate the most accurate results when using laser diffraction. WebA particle size analyzer operates according to a specific method of measurement (for example, image analysis, laser back-scattering, or laser diffraction) with individual and method-specific boundary conditions. There are a variety of particle size analyzers available. All particle size analyzers provide different values for the same particle ...
