What is the maximum viscosity for DLS?

Is there a maximum viscosity for DLS measurements?   The Malvern Zetasizer can determine particle size by dynamic light scattering (DLS). In this technique, the intensity fluctuations are analyzed to find the corresponding diffusion coefficient that led to the fluctuations….READ MORE >
