System for the characterization of colloids, nanoparticles and macromolecules.
Univ.-Prof. Dr. Oliver Brüggemann
The Zetasizer Nano ZSP is used for the measurement of size, electrophoretic mobility of proteins, zeta potential of nanoparticles and surfaces, and optionally the microrheology of protein and polymer solutions.
The exceptional performance also enables the measurement of the molecular weight and second virial coefficient, A2, of macromolecules and kD, the DLS interaction parameter.
Methods & Expertise for Research Infrastructure
The Zetasizer Nano ZSP is particularly suitable for the characterization of proteins and nanoparticles where the highest sensitivity for size and zeta potential measurement is required. It includes a Protein Measurement option for protein mobility measurements.
The system incorporates a two angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with ‘NIBS’ optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering.
