SZ-100V2

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.

Clear and simple multi-parameter analysis of nanoparticles!

Three analyzers in a single compact body deliver high-sensitivity, high-accuracy analysis of each measurement parameter.

Segment: Scientific
Produktionsfirma: HORIBA, Ltd.

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.

Wastewater Treatment Optimization with Zeta Potential
Wastewater Treatment Optimization with Zeta Potential
Suspended solids are a common impurity in wastewater from industrial and mining operations. In order for water clarity, the suspended solids are often allowed to settle. The duration of these processes is a strong function of the particle size. Thus, if particles can be made to aggregate, the settling process is shorter and the treatment operation is faster and less expensive.
