Scope
This document describes a method for particle size measurement of nanoparticles dispersed in multiphase systems using transmission electron microscopy image processing and analysis techniques. This document is applicable to particle size measurement and particle size distribution of nanoparticles in solid-phase multiphase systems. This document is also applicable to the particle size measurement of nanoparticles in colloids and biological tissues when the sample preparation meets the requirements of transmission electron microscopy observation.
