A quasielastic light scattering detector for chromatographic analysis

Review of Scientific Instruments, 1993
Very sensitive laser light scattering equipment has been designed to be used in conjunction with chromatographic column separation. The system is prealigned and fully computer controlled. It gives the hydrodynamic radius of the eluting particles on line during separation.

Quasielastic γ-ray scattering from pentadecane

Physical Review A, 1990
A recently developed M\"ossbauer instrument has been used to study the liquid dynamics of pentadecane at various temperatures and scattering angles. Widths of the quasielastic signal extracted from the data ranged between 16 GHz (at 12 \ifmmode^\circ\else\textdegree\fi{}C) and 48 GHz (at 74 \ifmmode^\circ\else\textdegree\fi{}C) at a scattering vector ...

Inelastic and quasielastic neutron scattering

Current Opinion in Solid State and Materials Science, 1997
Inelastic neutron scattering is a technique for measuring the dynamics of condensed matter on a microscopic scale. Several dynamical regimes can be probed, including atomic momentum distributions, vibrations, and relaxation phenomena. Recent work has been carried out to investigate the dynamics of disordered materials.

Particle Size Determination by Quasielastic Light Scattering

Analytical Chemistry, 1981
Sedimentation, microscopy, intensity light scattering, exclusion chromatography, and electrical resistance change are among the techniques rontinely used for particle size analysis. Ongoing studies with quasielastic light scattering (QLS) are demonstrating that this relatively new technique offers significant advantages in many pa:ticle sizing analyses

Quasielastic and Inelastic Neutron Scattering

1982
The neutron is a heavy particle compared to photons and therefore scattering spectroscopy using neutrons covers a unique range of frequency-spatial correlations. For inelastic experiments the far infra-red spectroscopic range up to ∼1000 cm-1 may be observed with sizeable wave vector transfers and phonon dispersion curves mapped out.
