Description:
The Zetasizer Nano S is suitable when high sensitivity and a wide size range are required. It is a particle sizer for improved detection of aggregates, measurement of small volumes, dilute samples or highly concentrated samples as well as a device for measuring molecular size and molecular weight.

Dynamic light scattering is used to measure particle and molecule size. This technique measures the diffusion of particles moving due to Brownian motion and converts the data into size and size distribution using the Stokes-Einstein relationship. Non-invasive back scattering (NIBS) technology ensures the highest sensitivity over the widest possible ranges of dynamic size and concentration.
