A comparative study is made of the use of transmission electron microscopy, dynamic light scattering, and acoustic spectroscopy for measuring the sizes of nanoparticles in stable colloidal solutions of Al2O3, TiO2, SiO2, and ZnO at different concentrations and mean nanoparticle diameters. For solutions containing dendritic agglomerates of nanoparticles along with individual nanoparticles, it is found that acoustic spectroscopy can be used to measure the sizes of individual nanoparticles and dynamic light scattering can be used to measure sizes of objects from a mass of nanoparticles and their agglomerates.
