Dynamic Light Scattering

Product Name Dynamic Light Scattering Product Overview English Introduction: Dynamic Light Scattering (DLS) is the most mainstream characterization technology for particle size and dispersity of nanocolloids and suspension systems. Based on Brownian motion and light scattering effect, it accurately calculates the hydrodynamic particle size and polydispersity index (PDI) of samples by detecting the dynamic diffusion behavior of particles in liquid, and intuitively reflects the size distribution uniformity and dispersion stability of nanoparticles and colloidal particles. As a non-destructive and rapid liquid-phase characterization method, it requires no complex pre-treatment and is suitable for various liquid-phase dispersion systems such as water-soluble powder, nano-suspensions, polymer emulsions and colloidal solutions. This testing service is equipped with Malvern Zetasizer Lab nano particle size analyzer, which is specially designed for scientific research-level fine particle size detection. The test parameters are optimized for water-phase dispersion systems with high data stability and repeatability. It is widely applied in nano material R&D, biomedical colloid quality control, emulsion formula optimization and chemical dispersion system stability analysis. The test results can be directly used for academic papers, project conclusion, patent application and industrial product quality inspection.
