WebThe light scatter is measured by two optical detectors. One detector measures scatter along the path of the laser (1). This parameter is referred to as forward scatter (FSC). The other detector measures scatter at a ninety degree angle relative to the laser (1). This parameter is called side scatter (SSC). WebRayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move …

WebWhen no particle is present in the laser beam, scattered laser light hits and is blocked by the obscuration bar. On the other hand, when a particle is present in the laser beam, laser light refracted (scattered) by the particle passes over the bar and triggers signal associated with that particle. WebWith SLS, laser light is directed at your sample and the scattered light is measured at one or more angles around the sample. Because the intensity of scattered light can be affected by a number of properties of your sample and setup, such as: We can use the measured intensity to characterize the particles in your sample.

WebDynamic light scattering is a well-established, standardized technique for particle size analysis in the nanometer range and has been used for about 40 years. DLS provides information on the mean particle size as well as on particle size distribution. It covers a broad size range from the lower nanometer range up to several micrometers.
