Colloidal particle sizing using various techniques — •Kathrin Eitel and Hans-Joachim Schöpe — Institut für Angewandte Physik, Tübingen

Nanoscience and nanotechnology are playing key roles in different scientific disciplines and its importance increased significantly over the last years. Particle size analysis is of essential importance in research and development as well as in industrial production. Different techniques are used for particle sizing, all given optimal results in a certain particle size range. In dispersions of nano- to micrometer-sized particles, DLS is commonly used. DDM might be a more exact alternative method for particle sizing. In this work, we compared DDM with the established methods such as DLS and SLS working out their advantages and disadvantages.

Keywords: colloids, SLS, DLS, and DDM.
