Abstract
Nanoparticles with diameters from 1 - 100 nm are used in large quantities f or very different applications. A precise determination of the important ph ysical quantities (which are responsible for the application properties) su ch as diameter, particle size distribution, and surface is therefore very e ssential. The most common methods for the determination of these quantities are analytical ultracentrifugation (AUC) and dynamic light scattering (DLS ). The paper demonstrates the techniques of getting a precise characterizat ion of nanoparticles and suggests a new method for the correction of the se dimentation coefficient and its distribution with respect to the diffusion coefficient.
