Postnova FFF and SEC Platform

The Postnova Field-Flow Fractionation (FFF) and Size Exclusion Chromatography (SEC) platform

The Postnova modular FFF and SEC platform can be configurated for any single or combination of several of the four FFF subtechniques - Asymmetric Flow FFF (AF4), Hollow-Fibre Flow FFF (HF5), Electrical FFF (EAF4), Centrifugal FFF CF3) and Thermal FFF (TF3). Because of this flexibility, it can be used for the separation, characterization and fractionation of nearly any macromolecule or nanoparticle. A separation module is available for each particular FFF technique but Postnova uses the same pumps, autosamplers, detectors, and fraction collectors, independently of the FFF technique. Thus adding, for example, CF3 capability to an AF4 system only requires adding a CF3 Separator Module. The NovaFFF software controls the complete FFF platform, acquires the data, and allows the direct calculation of concentration, molar mass and size.

The Postnova platform can be also configurated for Size Exclusion Chromatography (optional). You can easily switch from FFF to SEC and vice versa. The NovaFFF software takes care of control, data acquisition and calculation.
