HORIBA SZ-100V2 Product Features of the Nanoparticle Analyzer:

Particle size measurement range: 0.3 nm to 10 μm

The SZ-100V2 series employs dynamic light scattering (DLS) to measure particle size and distribution, enabling accurate measurements across an exceptionally wide concentration range—from parts per million (ppm) to concentrations as high as several tens of percent. It is compatible with commercially available sample cells and facilitates convenient measurement of trace samples.

Zeta potential measurement range: ?500 to +500 mV

Using HORIBA's micro-sample cell requires only 100 μL of sample. The stability of dispersed systems can be predicted and controlled through zeta potential values. Higher zeta potential indicates greater stability in dispersed systems, which is highly significant for formulation research.

Molecular measurement range 1×10³ ~ 2×10⁷

By measuring the static scattering intensity of samples at different concentrations and calculating the absolute molecular weight (Mw) and second-Villi coefficient (A2) via the Debye notation method.

HORIBA SZ-100V2 Measurement Principle of Nanoparticle Analyzer:

Principle of Particle Size Measurement

The HORIBA SZ-100V2 Nanoparticle Analyzer employs dynamic light scattering technology to measure particle size by detecting fluctuations in the intensity of scattered light over time. The Brownian motion of nanoparticles causes variations in light intensity, and statistical analysis of these fluctuations can be correlated with particle diffusion. Since the intensity of Brownian motion is significantly correlated with particle size, a relationship can be established between particle size and the fluctuations in scattered light intensity.

Principle of Zeta Potential Measurement (Laser Doppler Electrophoresis Method)

Most nanoparticles and colloidal particles suspended in a liquid carry surface charges. When an electric field is applied to the liquid, the charged particles move under the influence of the electric field. The direction and velocity of this motion depend on the particle's charge, the dispersion medium, and the electric field strength. By observing the Doppler shift in scattered light, the particle's velocity can be measured. This velocity is proportional to the potential across the particle's shear plane (i.e., the zeta potential). Therefore, the particle's zeta potential can be determined by measuring its motion under an electric field.

Principles of Molecular Weight Measurement

The HORIBA SZ-100V2 Nanoparticle Analyzer employs two methods to measure the molecular weight of macromolecules such as polymers, proteins, and starches. The first method utilizes particle size information obtained through dynamic light scattering and the Mark-Houwink equation. The second method is the Debye notation.
