nanoPartica SZ-100V2 Series

nanoPartica SZ-100V2 Series Spincotech

Nanoparticle Analyzer

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.

Features

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 and preparing Debye plots.

The SZ-100V2 Series applies sophisticated intelligence and learning capability to rapidly determine nanoparticle properties!
  • Since the SZ-100V2 Series analyzer covers a wide sample concentration measurement range, sample dilution and other preprocessing is nearly eliminated.
  • The use of a dual optical system enables measurement of high-concentration samples such as slurry and ink pigments as well as low-concentration proteins and polymers.
  • A single device analyzes the three parameters that characterize nanoparticles: particle size, zeta potential, and molecular weight.
  • HORIBA-developed cells for zeta potential measurement prevent sample contamination. Simple analysis by means of ultra micro-volume dedicated cells (volume as low as 100 μL). Suitable for analysis of dilute samples.
  • HORIBA-developed electrode for zeta potential cell made from carbon material, the material is not corroded by high salt samples such as saline.
