Refractive Index Effects on Particle Size Measurement in Liquid Media by Optical Extinction

Written by Katie Sternberg

When monitoring larger size particles, extinction optical particle counting is the typical method used for accurate results. The refractive index difference between microcontaminants and the liquid media being measured can be explored in an effort to determine the related extinction response. At submicron particle ranges, the index contract between a particle and the liquid media is important. The interplay of refractive index contrast and particle size analysis in liquids can be explored and described with the aid of Mie theory.
