    What is Particle Size Analysis? (Definition, Methods

    Particle size analysis is a process that involves an operator employing industry-standard equipment to determine the size and shape of the particles being worked with. It is an essential element to any reliable quality control protocol. That said, when particle size analysis is omitted from an operation, you run the risk of early product faults

    Aug 12, 2019 Laser diffraction has become one of the most commonly used particle sizing methods, especially for particles in the range of 0.5 to 1000 microns. It works on the principle that when a beam of light (a laser) is scattered by a group of particles, the angle of light scattering is inversely proportional to particle size (ie. the smaller the

    The larger the particle becomes, however, the more light that will be scattered forward (away from the light beam). Wavelength also affects light scatter. In general, shorter wavelengths will scatter more than longer wavelengths for the same particle size 32. Shorter wavelengths are also more susceptible to absorption by colored molecules in
