چکیده

This review provides a brief overview of particle size characterization by Ž . Sedimentationr Steric Field-Flow Fractionation SdrSt FFF and discusses the retention in steric FFF, the recent findings on hydrodynamic lift forces, and the density compensation calibration procedure for obtaining size distribution of supramicron-sized particles. A number of applications to the determination of particle size distribution are discussed with some practical considerations such as steric inversion diameter, size selectivity, and selection of an optimum calibration run condition.

Miniaturized flow fractionation device assisted by a pulsed electric field for nanoparticle separation.

Electric field flow fractionation (EFFF) is a powerful separation technique based on an electrical field perpendicular to a pressure-driven flow. Previous studies of microelectric field flow fractionation (micro-EFFF) indicate that separation performance was limited due to a weak effective electric field caused by polarization layers on the electrode surfaces. In this work, we report on a micro...

Combining gas-phase electrophoretic mobility molecular analysis (GEMMA), light scattering, field flow fractionation and cryo electron microscopy in a multidimensional approach to characterize liposomal carrier vesicles

For drug delivery, characterization of liposomes regarding size, particle number concentrations, occurrence of low-sized liposome artefacts and drug encapsulation are of importance to understand their pharmacodynamic properties. In our study, we aimed to demonstrate the applicability of nano Electrospray Gas-Phase Electrophoretic Mobility Molecular Analyser (nES GEMMA) as a suitable technique f...

Vesicle size distributions measured by flow field-flow fractionation coupled with multiangle light scattering.

The separation method, flow field-flow fractionation (flow FFF), is coupled on-line with multiangle laser light scattering (MALLS) for simultaneous measurement of the size and concentration of vesicles eluting continuously from the fractionator. These size and concentration data, gathered as a function of elution time, may be used to construct both number- and mass-weighted vesicle size distrib...

Particle size distribution measurements of manganese-doped ZnS nanoparticles.

We performed particle size and particle size distribution measurements for L-cysteine-stabilized ZnS/Mn nanoparticles in the size region below 10 nm. For this we applied transmission electron microscopy (TEM), analytical ultracentrifugation (AUC), dynamic light scattering (DLS), and asymmetric flow field flow fractionation (aF-FFF) measurements, and we calculated particle sizes with the help of...
