Dynamic light scattering method7/30/2023 So the plotting concentration on horizontal and Kc/R(θ), which is equivalent as a reciprocal number of scattering intensity, on vertical after measuring scattering intensities of variable concentrations is called Debye Plot.Since angle dependency of scattering intensity appears in the large molecular weight sample, measuring scattering intensity at variable angle(θ) provides more accuracy on molecular weight measurement and radium of gyration, which is yardstick of molecular dispersion.When measured at fixed angle, inputting expected radium of gyration, correcting as an angle dependent measurement, accuracy of molecular weight is improved. Dynamic light scattering (DLS) is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or. This well established principle is used in dynamic light scattering (DLS), or also called photon-correlation spectroscopy, which is a widely popular and highly adaptable analytical method applied in different fields of life and material sciences, as well as in industrial quality control processes. In reality, scattering intensity to be obtained depends upon concentration, too. To simplify, from the bigger particle gives the stronger scattering and the smaller particle gives weaker scattering. As a principle, molecular weight is calculated from absolute value of scattered light obtained by irradiated light into colloidal particle. Dynamic light scattering is a well-established, standardized technique for particle size analysis in the nanometer range and has been used for about 40 years. Static Light Scattering Method is renowned as the convenient method to know absolute molecular weight. Particle size analysis in the submicrometre size range is performed on a routine basis using the dynamic light scattering (DLS) method, which probes the.
