Postnova is the manufacturer of analytical instruments based on Field-Flow Fractionation (FFF). With an application range of 1 nm to 100 µm and 1000 Da up to many MDa, the Postnova platform is a great analytical tool for the separation/characterisation of particles, polymers, proteins, viruses, antibodies, liposomes or exosomes in complex aqueous/organic matrices. Postnova provides the complete range of FFF techniques including Asymmetrical FlowFFF, Electrical AF4, CentriFFF and ThermalFFF along with its detection systems as MALS, DLS, RI and ICP-MS.

Postnova Virus Characterization

Postnova Analytics has published an applications report that presents data from a collaboration with the Analytical Development group at Biogen Inc. on separation of a virus mixture using Asymmetrical Flow Field-Flow Fractionation (AF4) and measurement of their radius of gyration (Rg).
