Nanotechnologies. Evaluation of the mean size of nano-objects in liquid dispersions by static multiple light scattering (SMLS). | Status: Superseded, Withdrawn

1 Scope This document provides guidance and requirements for the determination of the mean (spherical) equivalent diameter of nano-objects (i.e. particles, droplets or bubbles) dispersed in liquids using the static multiple light scattering (SMLS) technique. The technique is applicable to a wide range of materials and does not require dilution of concentrated samples.
