Effects Of Particle Shape On Measured Particle Size

Particle size analysis is a commonly performed test with a broad range of applications encompassing virtually all industries. Numerous techniques exist for measuring particle size distribution, most of which express the results in terms of equivalent spherical diameter. However, when the particles are not spherical, different measurement techniques produce different particle size distributions for a given sample. Understanding what the particle size technique actually measures, how it performs the measurement, and the key assumptions around which the technique is based are crucial when selecting a particle size technique for your sample or application.
