I was surprised by the recent report of Crossley et al.' that the diffusion coefficient ( D T ) of polystyrene latex spheres exhibits an anomalous temperature dependence.
Most analyses of submicron particles using sedimentation field-flow ลฝ . fractionation SdFFF have been carried out in aqueous systems. However, a nonaqueous carrier solution could be suitable for SdFFF when the particle density is close to the density of water. Few papers have reported the retention
I t has long been assumed that the effect of temperature on the diffusion coefficient D , the sedimentation coefficient s , and other hydrodynamic parameters is correctly described by Walden's rule and its extensions, i.e., hydrodynamic properties of dilute solutions of macromolecules scale linearl
