Molecular weight measurement down to 980Da.Zeta potential of surfaces using accessory cell.Size measurement from 0.3nm (diameter) to 10 microns using patented NIBS (Non-Invasive Back Scatter) technology.Exceptional sensitivity for the zeta potential measurement of proteins and nanoparticles using patented M3-PALS.Active Questions & Answers Ask a Question The flow mode option enables the system to be connected to an SEC or an FFF system to use as a detector for the size of proteins or nanoparticles.Ī choice of cuvettes are available, from disposable single-use to specific cells for viscous or high concentration samples or measuring the zeta potential of surfaces. In addition, a microrheology option is available for measuring sample viscosity and viscoelastic properties, Using Non-Invasive Backscatter optics (NIBS) it has significantly better performance than systems using 90 degree scattering 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. 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. It includes a Protein Measurement option for protein mobility measurements. The Zetasizer Nano ZSP is the world’s highest performance system and particularly suitable for the characterization of proteins and nanoparticles where the highest sensitivity for size and zeta potential measurement is required.
