Particle Size Analysis | RTI Laboratories

Particle sizing is a method of determining size characteristics of the target particles. Several methods are available to adequately size the particles, such as light extinction, sieve analysis, and microscopic analysis. Light scatter involves suspending the particles in a liquid medium such as water or an organic solvent.
