Sanyo Trading Co., Ltd

Sanyo Trading Co., Ltd. Exhibit Products
Optimization of the dispersion system is important for maintaining high quality, stability, and high functionality, and for this purpose, it is necessary to accurately understand the dispersion state. The factors that govern the dispersion state are mainly particle size, zeta potential, wetting of the particle interface, rheology, and stability. Taking advantage of our characteristics as an import trading company, Sanyo Trading imports and sells equipment that can evaluate these characteristics from excellent analytical equipment manufacturers around the world. In addition to laboratory use, we also offer online, inline, and explosion-proof models, providing customers with a total solution for distributed evaluation.

1. Particle Size Distribution and Zeta Potential
1)Model：Acoustic and Electro-acoustic particle size & Zeta potential analyzer　（DT-1202）
・Overview：
When ultrasonic waves are applied to a particle dispersion system, the attenuation at each frequency changes depending on the particle size and distribution present in the dispersion system. This property is used to measure particle size. Additionally, when particles are vibrated by ultrasonic waves, the diffused electric double layer causes a polarization phenomenon due to the density difference between the particles and the continuous phase solvent. The current generated by this phenomenon is called colloid vibration current (CVI), and the zeta potential is measured by measuring this colloid vibration current.
・Features：
- no dilution required: 0.1 to 50 vol%
- Particle size range: 5nm-1000μm (Zeta potential <100μm)

At this conference, we will introduce particle size distribution and zeta potential meters and small angle X-ray scattering (SAXS) instruments as tools for analyzing colloid structure, as well as rheometers as tools for analyzing rheological properties.

[Particle size analyzer/zeta potential analyzer]
Anton Paar offers two different measurement principles for characterizing particles from the nm to mm range. The Litesizer series uses light scattering to measure the particle size of nanoparticles and microparticles in dispersions as well as the zeta potential, transmittance, molecular weight, and refractive index.
The PSA series uses laser diffraction and scattering to measure particle size in dispersions and dry powders from the μm to mm range. These two products enable comprehensive and comprehensive particle　characterization.

Solid surface zeta potential measured with SurPASS™ 3 allows prediction of electrostatic attraction or repulsion between solutes and solid surfaces. Furthermore, the Litesizer™ can measure the zeta potential of nanoparticles, which is commonly used as an indicator of the stability of colloidal dispersions. Zeta potential generally describes the surface charge and functionality and is a prerequisite for determining the isoelectric point of a substance. In addition to the traditional applications of zeta potential, Anton Paar has established correlations to the conductivity, porosity, and swelling of materials.

[Small Angle X-ray Scattering(SAXS)]
Anton Paar's small-angle X-ray scattering systems SAXSpoint 5.0 and SAXSpace employ excellent X-ray sources and optics to generate X-ray beams with excellent spectral purity and flux. Parasitic scattering-reduced beam collimation in combination with state-of-the-art hybrid photon counting (HPC) detectors ensures high signal-to-noise ratios and excellent overall data. They also offer the most comprehensive and versatile sample stages for nanostructured samples. Whether you are studying nanostructured surfaces, performing tensile tests, structural studies under temperature/humidity/pressure control, or gas response measurements, Anton Paar's SAXS/WAXS/GISAXS/RheoSAXS systems offer the ultimate flexibility for characterizing nanostructured samples.

[Rheometer & Rheo-PI Option]
The latest MCR rheometer series first and foremost further expands the range of possibilities for rheological measurements. Whatever your current and future rheological requirements, the modularity of the MCR rheometers means they can be efficiently and easily adapted and expanded along with your needs, from routine quality control to high-end research and development. Investing in an MCR rheometer is a safe investment in technology with a long history. For example, the air-bearing-supported EC motor was developed by Anton Paar and has been used in all MCR models for over 25 years, ensuring precision over a wide viscosity range. This allows you to measure liquids with viscosities even lower than water and characterize hard materials such as polymer composites and steel with DMA measurements, and everything in between.

Anton Paar Japan and Photonic-lattice have jointly developed a new rheo-optical measurement system (Rheo-High-speed Polarization Imaging, Rheo-PI) based on two-dimensional polarization analysis. By introducing a polarized high-speed camera to the rheometer, it is now possible to measure the shear-induced phase transition of emulsion dispersions under shear flow, as well as the retardation distribution and orientation axis distribution of the orientation properties in real time.
In this technical seminar, we will introduce the overview and principle of this device, as well as measurement examples.
