Postnova Analytics reports on a recent independent review which details how Asymmetric Flow Field Flow Fractionation (AF4) is a valuable technique to improve the quality of nanoformulated medicines.

Its lower surface area, gentler shear forces and lack of a stationary phase make the FFF channel ideally suited for the separation of large particles and polymers, particularly those that do not ...

Field-flow fractionation (FFF) is a versatile means of size- based separations, capable of fractionating viral particles, liposomes, and lipid nanoparticles, proteins, and more. The Eclipse TM system ...

Current regulations for nanomedicines overlook the effects of the different forms of the same element, such as ions, nanoparticles, and aggregates. In a recent study, researchers developed a new ...

Size-exclusion chromatography (SEC), also known as gel-permeation chromatography (GPC), has become the dominant technique for the determination of molar mass distributions of synthetic and natural ...

Postnova Analytics has reported how its latest generation of Asymmetrical Flow Field Flow Fractionation (AF4) systems are providing labs worldwide with a technique to characterize and quantitate virus ...

Conceptual image of the separation of nanoparticles (active ingredients) and ions (elemental impurities) in nanomedicines using an asymmetric flow field-flow fractionation system. Nanomedicines, ...
