  Chemistry and Biotechnology - Zeta-potential & Particle size Analyzer ELSZ-2000 series



Zeta-potential & Particle size Analyzer ELSZ-2000 series

In addition to existing zeta potential and particle size measurement, molecular weight analysis function is newly added. (Particle size : 0.6nm-10um/Concentration range: 0.00001%-40%). Electro-osmosis measurement enables high precision analysis of zeta potential using micro-volume (130ul) disposable cell. Furthermore new auto temperature gradient function with extended range between 0 and 90°C makes melting point and phase transition point analysis possible.
Features:
icon Higher sensitivity and shorter measure time with new APD.
icon Melting point and phase transition point analysis enabled by auto temperature gradient function.
icon Wide temperature range between 0 and 90°C
icon Wide range Molecular weight analysis
icon Supports concentrated sample measurement
icon High precision zeta potential analysis thanks to electro-osmosis measurement and plot analysis
icon Supports zeta potential measurement of salt condensed sample.
icon Surface zeta potential of smaller area sample

Principle:
Particulates dispersed in a solution are normally subject to Brownian motion. The motion is slower with larger particles and faster with smaller particles. When laser light illuminates particles under the influence of Brownian motion, scattered light from the particles shows fluctuation corresponding to individual particles. The fluctuation is observed according to the pinhole type photon detection method so that particle size and particle size distributions are calculated.
