NS-90 Nanometer Particle Size Analyser Introduction
NS-90 nanoparticle size analyzer is a cost-effective characterization technology for nanoparticles. It is suitable for applications requiring high sensitivity of particle size measurement or using the same results as 90 degree scattering angle system. The instrument is suitable for the analysis of emulsion, suspension, protein and other samples.
The instrument uses 90 degree dynamic light scattering technology to measure particle and molecular size, and static light scattering method to measure the molecular weight of protein and polymer; in many domestic brands, it is exclusively equipped with avalanche photodiode (APD) detector, which is much more sensitive than photomultiplier tube detector (PMT); it also uses high-end He-Ne gas laser, coupled with precise internal temperature control technology, and is compact. Closed-light path and advanced software algorithm ensure data repeatability, accuracy and 0.3 nanometer test lower limit; at the same time support SOP standard operation, as well as intelligent evaluation of measurement data, convenient for users to use.
