This year, to help celebrate the 60th birthday of field-flow fractionation (FFF), scientists are gathering at the Herbert Hoover Building in Washington, DC from May 17-20, 2026 for the 24th ...

Postnova Analytics reports on an informative new book** that introduces scientists to thermal field-flow fractionation and discusses its advantages over the fundamental problems associated with ...

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 ...

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 ...

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

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 ...

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 ...
