Postnova Analytics powerful EAF4 technology combines the principle of Electrical and Asymmetrical Flow Field-Flow Fractionation in just one system. Electrical and Cross Flow Fields can now be applied ...

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 ...

The separation channel is a key component in asymmetric-flow field-flow fractionation, also referred to as AF4 or FFF. In FFF, chromatographic separation takes place in a trapezoidal channel which ...

Field-flow fractionation (FFF) encompasses a suite of separation methods in which an external field applied perpendicular to a laminar flow channel drives sample components to different streamlines ...

Nanomaterials are surging in interest for a variety of applications: medicine, agriculture and more. However, the environmental effects of nanoscale materials such as nanoplastics are of increasing ...

In this panel discussion, four leading FFF experts share their perspectives on where the technique stands today and where it ...

Separation of particles is conducted based on their size (hydrodynamic radius) using differences in diffusion coefficients. The particles are accumulated at different heights in the AF4 channel.

Wyatt Technology, the world leader in instrumentation for absolute macromolecular and nanoparticle characterization, reveals the launch of its 6 th-generation Eclipse™ FFF system that represents an ...

Nanoparticles exhibit unique chemical and physical properties that underpin their widespread use in medicine, electronics, environmental remediation and consumer products. To harness these ...

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