Nanolink SZ901 纳米颗粒分析仪
介绍
The Nanolink SZ901/902 series of nano particle size and Zeta potential analyzers is another pinnacle in the field of dynamic light scattering (DLS) particle characterization after the SZ900 series. Compared with traditional analytical instruments, it has many innovations in light beam splitting, beam combination and frequency shift algorithm, which greatly improves the mechanical reliability of the measurement system and the measurement accuracy of light scattering signal and electrophoretic mobility, and significantly improves the repeatability of nanometer particle size and Zeta potential. It is suitable for particle size and Zeta potential analysis of various samples such as organic or inorganic nanoparticles, emulsions, polymers, micelles, viral antibodies and proteins.

Key features include:
◆ Includes classical 90°, backward and forward dynamic light scattering techniques to measure 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
◆ With automatic constant temperature technology, the highest power can reach 50mW, wavelength 638nm solid laser light source, the instrument is ready to use
The original cosine fitting method (CFLS) is better than the current spectrum analysis (快速傅里叶变换) and phase analysis (PALS).
◆ Original integration of laser light source, illumination light and reference light and fiber beam splitting technology
◆ Original fiber beam and interference technology of signal light and reference light
◆ Integrated optical fiber technology with high sensitivity and extremely low dark current (20cps) photon detector
◆ Conventional temperature control range can reach -15°C~120°C, accuracy ±0.1°C
◆ New generation of high-speed digital correlator, dynamic range greater than 10¹¹
◆ Condensation control – dry gas purge technology
