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.
