A short introduction to Postnova’s Field-Flow Fractionation (FFF) platform. This includes: Asymmetric Flow FFF (AF4) which separates by size, Electrical AF4 (EAF4) which separates by size and charge, Centrifugal FFF (CF3) which separates by mass, and Thermal FFF (TF3) which separates by molecular weight and chemical composition. The size exclusion chromatography (SEC) option provides possibilities for orthogonal data. Detectors for FFF and SEC include refractive index, UV/Vis, multi-angle light scattering, dynamic light scattering, viscometry, inductively coupled plasma mass spectrometry, and more.

A short introduction to the principle and applications of multi-angle light scattering from Postnova Analytics. The combination of having 21 scattering angles, more low scattering angles than any other detector, and the Clean By Design cell, results in superior sensitivity, precision, accuracy, and robustness.


Postnova Analytics’ Founder and CEO, Thorsten Klein, discusses the versatility of Field-Flow Fractionation (FFF). This technique, which uses an open flow channel to separate particles and molecules larger than what can be achieved with column chromatography, can be coupled with a wide variety of detectors. These detectors include multi-angle light scattering, dynamic light scattering, and inductively coupled plasma mass spectrometry, making FFF a very powerful separation technique. As a result, it is used for a variety of applications in biology, chemistry, nanomedicine, and more.

Postnova Analytics presents this webinar on Field-Flow Fractionation (FFF), a versatile family of methodologies that can be used to characterize a multitude of sample types. FFF’s ability to separate a large range of particle sizes and interface to a wide range of detectors makes it amenable to numerous applications, including measurements of size, shape, zeta potential, elemental composition, and aggregation.
