• Particle size – the system enables measurements of particles and molecules from 0.6nm to 6 microns.
• Zeta potential – the system enables accurate measurements of zeta potential in aqueous and non-aqueous dispersions.
• Molecular weight – the system gives the sensitivity and stability required for absolute molecular weight measurement.

Zetasizer Nano ZS is capable for accurate, reliable and repeatable size analysis including protein melting point determination. Non-invasive back scatter technology takes particle sizing to new levels of sensitivity in the 0.6nm to 6 micron range.

— Proteins and polymer analysis
— Little or no dilution necessary
— Pharmaceuticals
— Nanoparticles
— Optoelectronics

Zetasizer Nano ZS offers the highest sensitivity, accuracy and resolution of zeta potential. Even samples of very low mobility can be analyzed and their mobility distributions calculated.

— Emulsion stability
— Formulation stability
— Water treatment
— Pigment performance
— Impurity determination

Using static light scattering (SLS) and the classical Debye plot Zetasizer Nano ZS determines the molecular weight of random coiled polymers up to 5 x 105 Da as well as globular polymers and proteins up to 2 x 107 Da without the necessity for multi-angle measurement.
