WebOur dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. We also offer unique instruments for electrophoretic light scattering (MP-PALS), differential refractometry and differential viscosity. +1 805-681-9009 Headquarters 6330 Hollister Ave, Santa Barbara, CA 93117 WebAbstract. We introduce dynamic light scattering imaging (DLSI) to enable the wide-field measurement of the speckle temporal intensity autocorrelation function. DLSI uses the full temporal sampling of speckle fluctuations and a comprehensive model to identify the dynamic scattering regime and obtain a quantitative image of the scatterer dynamics.
WebDynamic light scattering (also known as photon correlation spectroscopy or quasi-elastic light scattering) is a technique which can be used to determine the size-distribution profile of small particles in suspension. The size range of analysis ranges from a few nanometers to a few micrometers. These measurements can be done on suspensions … WebUnderstanding Dynamic Light Scattering. When in solution, macromolecules are buffeted by the solvent molecules. This leads to a random motion of the molecules called Brownian motion. For example, …
