The Nanolink SZ901 Nano particle size and zeta potential analyzier is a new generation of nano particle size and zeta potential analyzer developed by Linkoptik Instruments on the basis of SZ900 based on years of scientific research. It adopts dynamic light scattering (DLS) and electrophoretic light scattering (ELS) principles to measure nano particle size and Zeta potential respectively It is widely used in particle characterization of samples such as organic or inorganic nano particles, emulsions, polymers, micelles, viral antibodies and proteins, as well as the detection and analysis of sample system stability and particle aggregation tendency.
Performance and Features:
-
Classic 90° dynamic light scattering technique measures particle size, covering a measurement range of 0.3nm – 15μm
-
Laser Doppler electrophoresis technology is used for Zeta potential analysis, which can accurately predict the stability of the dispersion system and the tendency of particle agglomeration
-
The maximum power of the automatic constant temperature technology can reach 50mW, the solid-state laser light source with the wavelength of 638nm, the instrument is ready to use
-
Original integration of laser light source, illumination light and reference light and fiber beam splitting technology
-
Original fiber combining and interference technology of signal light and reference light
-
High sensitivity and very low dark current (20cps) photon detector with integrated fiber optic technology
-
The normal temperature control range can reach -15°C- 120°C, and the accuracy is ±0.1°C
-
Next-generation high-speed digital correlator with a dynamic range greater than 10¹¹
-
