NanoZS (ZetaSizer) and Titrator MPT-2 (Malvern)

Page author : Delphine Tisserand.

This device allows the measurement of the diameter of nanoparticles as well as their surface charge at varying pH values.

NANO-ZS (ZETA-SIZER) AND TITRATOR MPT-2 (MALVERN)
Framework for use Device used within the framework of research projects at ISTerre and OSUG, or within the framework of external services.
Technical specifications Types of samples
Spherical particles between 0.3 nm and 10 µm.

Technical data
Detection of Brownian particle movements by a red laser (632.8 nm).
Analysis time on the order of a few minutes Concentration range : 100 to 400 mg/L .
Minimum quantity : 12 µL.

Types of Analysis
Hydrodynamic diameter measurements of suspended spherical particles (principle of dynamic light scattering) and surface charge measurements of these particles (zeta potential). The instrument is also equipped with a titrator that allows the pH to be varied during acquisition (obtaining the zero charge point).
