Overview

The SZ902 nanometer laser particle sizer is another high-performance dynamic light scattering nanometer particle sizer product launched after the SZ901. It uses a new automatic zoom technology to achieve multi angle measurement of nanometer samples. It can quickly measure the particle size and Zeta potential of various organic or inorganic nanometer particles, lotion, polymers, micelles, virus antibodies, proteins and other nanometer samples with different concentrations without dilution.

Product Details

Nanolink SZ902 seriesNano laser particle size analyzerFollowing the SZ901 seriesNano Particle AnalyzerLater, a new high-performance dynamic light scattering nano particle size meter was launched, which combined with the newly developed automatic focusing technology of Truth Optics, and realized the multi angle measurement of nano samples. It can quickly measure the particle size and Zeta potential of nano samples with different concentrations without dilution, and is very suitable for particle size and Zeta potential research level analysis and testing of various organic or inorganic nano particles, lotion, polymers, micelles, virus antibodies, proteins and other samples.

Nanolink SZ902Nano Particle AnalyzerThe outstanding performance and main features include:

◆ Includes classic 90 °, backward and forward dynamic light scattering techniques to measure particle size, with a measurement range covering 0.3nm-15 μ m*

Laser Doppler electrophoresis technology is used for Zeta potential analysis, which can accurately predict the stability of dispersed systems and the tendency of particle aggregation

Equipped with automatic temperature control technology, the highest power can reach 50mW, and the solid-state laser light source with a wavelength of 638nm can be used immediately

The innovative cosine fitting phase analysis method (CF-PALS) is superior to the current spectrum analysis method (FFT) and traditional phase analysis method (PALS)

◆innovativeIntegration of laser light source, illumination light and reference light, and fiber optic beam splitting technology

◆innovativeFiber Combining and Interference Technology of Signal Light and Reference Light

A photon detector with high sensitivity and extremely low dark current (20cps) integrated with fiber optic technology

The conventional temperature control range can reach -15 ° C~120 ° C, with an accuracy of ± 0.1 ° C

The new generation of high-speed digital correlators has a dynamic range greater than 10 ¹¹

◆ Condensation control - dry gas blowing technology
