Dynamic Light Scattering with Zeta Potential

Overview

The Zetasizer Nano ZS (Zen 3600) is a high performance particle and molecular size analyzer that uses dual angle Dynamic Light Scattering (DLS) with Non-Invasive Back-Scattering (NIBS) optics.

The system can also incorporate molecular surface charge information via its Zeta-Potential analyzer.

Suitable for measurement of size, molecular weight, mobility, and zeta potential of dispersed particles and molecules in solution.
