Zeta-potential & Particle size Analyzer ELSZneo
ELSZneo is the high-end model of the ELSZ series. This instrument measures the zeta potential and particle size of both diluted and concentrated solutions, and the molecular weight of a polymer. As new features, ELSZneo provides a multi-angle measurement to improve the separability of particle size distribution, particle concentration measurement, microrheology measurement, and gel network analysis.
Main features
◎ Particle size and zeta potential measurement in a wide concentration range from diluted to concentrated solution
◎ Multi-angle measurement to carry out particle size distribution with higher separability
◎ Zeta potential measurement of solid surface in high salt concentration
◎ Particle concentration analysis using Static Light Scattering
◎ Microrheology measurement using Dynamic Light Scattering
◎ Gel network and gel heterogeneity analysis by measuring the intensity of scattered light and diffusion coefficient of the sample at multiple points

Polymer Phase Structure Analyzer PP-1000
PP-1000 analyzes the structure of polymers and film in-situ (on site) and in real time by using the small angle light scattering method. This analyzer is able to analyze larger structures (μm order) compared to analyzers that use x-rays and neutron beams because it uses visible light.
Evaluation of optical anisotropy and analysis of spherulite diameter of crystalline film can be carried out from Hv scattering which uses polarizers. Analysis of polymer blend correlation length can be carried out from Vv scattering.
Main features
◎Measures scattering angle of 0.33 to 45 degrees in 10 msec at the fastest ※
◎Evaluates structures of submicron to several hundred micron size
◎Measures solution samples with specialized cells
◎Allows user to easily switch between Hv and Vv scattering with software
