Size Determination Of Vitamin B1 By Dynamic Light Scattering
2016-01-11 11:55:19| oilandgasonline Downloads
Dynamic light scattering (DLS) is a physics technique used for characterizing the size of particles and molecules in suspension and solution. The technique is based on the measurement of the time-dependent fluctuations in the intensity of the scattered light signals. The particles are responsible for the scattering of the light, while it is the random motion of the particles that produces the fluctuations in that scattering. By measuring the scattering, the particles' velocity can be derived, and from that velocity the hydrodynamic diameter of the particles can be calculated by using the Stokes–Einstein equation.

Dynamic Light Scattering Measurements On Latex Standards
2016-01-11 11:50:37| chemicalonline Downloads
Dynamic light scattering (DLS) is used to measure the size of small particles in suspension and of macromolecules in solution. When light is passed through such a sample, the particles scatter the light. Because the particles are constantly moving, the scattering intensity in any one direction fluctuates according to the particles' velocity. Since a particle's velocity depends on its size, the particle size in a given sample can be derived from DLS measurements. In this Application Report, we use polymer latex spheres ranging from 22 nm to 9200 nm in diameter to verify the DLS performance.
