A highly advanced analyzer solves the mysteries of the nano-world. A single device analyzes the three parameters that characterize nanoparticles: particle size, zeta potential, and molecular weight. Nanotechnology research and development is a continuously evolving effort to control substances at the atomic and molecular level in order to achieve new and better materials and products. The miniaturization of components – that is, control at the nano-level – is necessary to achieve faster, higher-performance devices and functions and to reduce energy consumption. Nanotechnology has come to play a key role in wide-ranging fields that affect our daily lives, including food, cosmetics, and the life sciences. Particle Size Measurement Range 0.3 nm to 10 µm The SZ-100V2 Series measures particle size and particle distribution width by dynamic light scattering (DLS). Analysis across a wide range of sample concentrations: Measurement of samples ranging from low ppm-order concentrations to high-concentration samples in double-digit percentages is possible. Accepts commercially available sampling cells. Analysis of small-volume samples is also possible. Zeta Potential Measurement – 500 to + 500 mV Analysis of sample volumes as small as 100 μL using HORIBA-developed microelectrophoresis cells. Use the value of zeta potential to predict and control dispersion stability. High zeta potential magnitudes indicate a stable dispersion, useful for formulation work. Molecular weight 1 × 103 to 2 × 107 Da Absolute molecular weight (Mw) and the second virial coefficient (A2) are obtained by performing static light scattering measurement as a function of sample concentration
