Particle size analysis — Dynamic light scattering (DLS)

Analyse granulométrique — Dispersion lumineuse dynamique (DLD)

Abstract / scope

This document specifies the application of dynamic light scattering (DLS) to the following:

—     measurement of average hydrodynamic particle size;

—     measurement of the size distribution of mainly sub micrometre-sized particles, emulsions or fine bubbles dispersed in liquids.

This document is applicable to the measurement of a broad range of dilute and concentrated suspensions.
