HORIBA SZ-100V2 Nanoparticle Analyzer

HORIBA Nanoparticle AnalyzerIntroduction:

A simple and compact device can simultaneously characterize three parameters of nanoparticles: particle size, Zeta potential, and molecular weight.

The development of nanotechnology is a continuous process of controlling substances at the molecular and atomic levels to obtain new, good, and superior materials and products. In order to obtain efficient and high-performance products while reducing energy consumption, HORIBA has launched the SZ-100V2 nanoparticle analyzer. This instrument can perform multi parameter analysis on nanoparticles through simple operation! By presenting the stability of nanoparticle size and dispersion system with simple and precise technology, we open the door to the advancement of nanotechnology for you!

HORIBA Nanoparticle AnalyzerCharacteristics:

Particle size measurement range: 0.3nm~10 μ m

The SZ-100V2 series adopts the principle of dynamic light scattering (DLS) to measure particle size and distribution, achieving sample measurement over a wide concentration range. Whether the concentration is in the ppm level or as high as tens of percent, it can be accurately measured. Commercial sample pools can be used. Measuring trace samples is also extremely convenient.

Zeta potential measurement range -500~+500mV

Using HORIBA's micro sample pool, the sample size is only 100 μ L. The stability of dispersed systems can be predicted and controlled by the Zeta potential value. The higher the Zeta potential, the more stable the dispersion system, which is of great significance for formulation research.

Molecular measurement range 1 × 103~2 × 107

By measuring the static scattering intensity of samples with different concentrations and calculating the absolute molecular weight (Mw) and second virility coefficient (A2) using the Debye point method.

HORIBASZ-100V2's ultra-high intelligence and learning ability in nanoparticle analysis can quickly determine the characteristics of nanoparticles for you!

The SZ-100V2 series has a wide range of measurable sample concentrations, so there is almost no need to dilute or otherwise process the samples. The dual path system (90 ° and 173 °) is designed to measure both high concentration samples such as glazes and pigments, as well as low concentration samples such as proteins and polymers.

Integrating the measurement of three major parameters that characterize nanoparticles: particle diameter, Zeta potential, and molecular weight.

The disposable Zeta potential measurement sample cell developed by HORIBA can eliminate sample contamination. The dedicated ultra trace sample pool (minimum capacity 100 μ L) is simple and easy to use, and suitable for analyzing diluted samples.

The Zeta potential specific graphite electrode developed by HORIBA can be used to measure highly corrosive high salt samples.

Measurement principle of HORIBASZ-100V2 nanoparticle analyzer:

Principle of particle size measurement

The HORIBASZ-100V2 nanoparticle analyzer uses dynamic light scattering technology to measure particle size, by measuring the fluctuation of the scattered light intensity of particles over time. The Brownian motion of nanoparticles causes fluctuations in light intensity, which can be statistically analyzed in relation to particle diffusion. Due to the significant correlation between the intensity of Brownian motion and particle size, a relationship can be established between particle size and fluctuations in scattered light intensity.

Zeta potential measurement principle (laser Doppler electrophoresis method)

Nanoparticles and colloidal particles in suspension mostly have surface charges. When an electric field acts on a liquid, charged particles will move under the influence of the electric field. The direction and speed of motion are related to the particle's charge, dispersion medium, and electric field strength. Measure the velocity of particles by observing the Doppler shift of scattered light. The velocity of particle motion is directly proportional to the potential on the particle shear plane (i.e. Zeta potential), so the Zeta potential of particles can be obtained by measuring their motion under the action of an electric field.

Principle of molecular weight measurement

The HORIBASZ-100V2 nanoparticle analyzer uses two methods to measure the molecular weight of macromolecules such as polymers, proteins, and starch. The first method uses particle size information obtained from dynamic light scattering and the Mark Houwink equation. The second method is the Debye notation method.
