But unlike dynamic light scattering technology, static light scattering technology is used to measure the time average intensity of scattered light over a period of time. Similar to dynamic light scattering, when laser irradiates particles in the sample, the particles scatter in all directions. Static light scattering is a non-invasive technique for characterizing molecules in solution.

NS-90 nanoparticle size analyzer uses static light scattering (SLS) technology to measure the molecular weight of proteins and polymers.

Particle size measured by this technology is the diameter of hard sphere diffused at the same speed as Photoelectric detector to measure the scattering light intensity fluctuation signal generated byīrownian motion of particles in the sample, then obtains the Correlation Function through the digitalĬorrelator, finally use Stokes Einstein equation to calculate the particle size and distribution. NS-90 nanometer particle size analyzer uses 90 ✬ dynamic light scattering technology, utilizes Dynamic light scattering (DLS) technique, also known as photon correlation spectroscopy (PCS), used to measure particle size by using the relationship between diffusion velocity and particle size. In the same time, if the displacement is small and the particle position is close, the particle size in the sample is larger on the contrary, if the displacement is large and the particle position changes greatly, the particle size in the sample is smaller. This movement has been going on all the time, so after we take a 'picture' of the sample motion at a short interval, we can see how much the particle moves and calculate how big it is. Small particles move faster in liquid than large particles. Random Brownian motion of particles in liquids is produced by collision of solvent molecules around them. NS-90 nanoparticle size analyzer uses dynamic light scattering technology to measure particle size and molecular size.

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. 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 uses high-end He-Ne gas laser, coupled with precise internal temperature control technology, and is compact. It continues to introduce and absorb the advanced particle characterization technology of Malvern Panalytical Company and combines the market application characteristics and needs of Chinese users. NS-90 nanometer particle size analyzer is a leading nanometer particle size analyzer specially developed by zhengzhoiu nanbei Instruments Company after the successful launch of TopSizer high-performance laser particle size analyzer in 2014. This machine is suitable for the analysis of emulsion, suspension, protein and other samples. It is suitable for applications requiring high sensitivity of particle size measurement or using the same results as 90 degree scattering angle system. Purpose: NS-90 nanoparticle size analyzer is a cost-effective characterization technology for nanoparticles.
