A somewhat wider size distribution for methods that need particle size uniformity between monodisperse (highly uniform <5% CV) and polydisperse (widely distributed <12% CV). These include instruments for light blockage, laser diffraction, acoustical imaging, electrolyte displacement or other methods used for analyzing wide size range materials.
