Effect of needle‐like crystal shape on measured particle size distributions

The effect crystal morphology has on measured particle size distributions (PSDs) is explored, with a focus on particles exhibiting a needle‐like habit. An idealized in silico study was performed, targeted at modeling the measurement principles of various particle sizing devices, namely laser diffraction, Coulter counter, focused beam reflectance measurement, a single and a dual projection imaging devices. The evolution of a crystal population is...
