Particle size determination using static light scattering (laser diffraction) is currently the most versatile and popular technique for the majority of polymeric materials. Since extruded polymer pellets can exceed the upper size limitation of laser diffraction these materials are typically measured via dynamic image analysis. The combination of laser diffraction and dynamic image analysis systems supplies a wide dynamic range (0.01 µm t
