ELSZneo is the high-end model of the ELSZ series. This instrument measures zeta potential and particle size of both diluted and concentrated solutions, and 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.
The zeta potential flat surface cell adopted a newly developed coating which enables measurement in a high salt concentration such as physiological saline. With the brand-new flat surface cell and ultra-micro volume cell that can measure particle size with a 3 μL of sample, ELSZneo is expanding the potential in the life science field.
Features
- Particle size and zeta potential measurement in a wide concentration range from diluted to concentrated solution (~ 40%)
- 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 intensity of scattered light and diffusion coefficient of sample at multiple points
- Standard flow cell which can be used for two types of measurement (Particle size and zeta potential) without replacing samples
- Wide range of measurement temperature from０to 90℃
- Temperature gradient function which enables denaturation (melting temperature) analysis for proteins
- Electrophoretic mobility measurement and plot analysis for accurate zeta potential measurement
- Band-pass filter (option)
