The diffusion coefficient for a suspension of monosized particles can be measured directly by photon correlation spectroscopy [12] (quasielastic light scattering). For distributions of different particle sizes, the average diffusion coefficient is determined by photon correlation spectroscopy. [Pg.504]

The porosity is not a separate factor for diffusion measurements using techniques such as pulsed field gradient nuclear magnetic resonance spectroscopy and some modes of quasielastic light scattering in which the diffusivity is determined from the mean-square displacement of solutes ... [Pg.304]

In 1953, Stockmayer and Fixman observed that the ratio, h, of hydrodynamic or Stokes radii (/ h) of the branched and linear macromolecules could also be used as a measure of branching. The relatively recent introduction of online quasielastic light scattering (QELS, also known as dynamic light scattering and as photon correlation spectroscopy) detectors for SEC permits direct determination of h by... [Pg.1419]

QELS stands for quasielastic light scattering. It was the name first given to the technique because, when photons are scattered by mobile particles, the process is quasielastic. QELS measurements yield information on the dynamics of the scatterer this gave rise to the acronym DLS, which stands for dynamic light scattering. Finally, since most measurements are made with a digital correlator, the acronym PCS, which stands for photon correlation spectroscopy, is widely used. [Pg.173]

Dynamic processes at thermodynamic equilibrium that occur within a time range from sub-microseconds to seconds can be probed without the imposition of a transient disturbance by optical intensity fluctuation spectroscopy. As such, dynamic light scattering (DLS) [155] measures the fluctuation of quasielastic scattering intensity and fluorescence correlation spectroscopy (FCS) [156-158] measures concentration fluctuations of specific fluorescent molecules... [Pg.136]
