Postnova, founded in 1997 as a Spin-Off from Technical University Munich and now located in Landsberg am Lech, Germany with subsidiaries in Salt Lake City, USA, and Malvern, UK, is the leading manufacturer of analytical instruments based on the principle of Field-Flow Fractionation (FFF). With an application range of 1 nm to 100 µm and 1000 Da up to several MDa, FFF is indisputably one of the most potent and flexible analytical tools for the fractionation of organic and inorganic nano- and microparticles as well as synthetic and biological polymers, proteins, viruses, antibodies, liposomes or exosomes both in complex aqueous and organic matrices. To cover these various applications, Postnova provides the complete range of FFF instrumentation including Asymmetrical Flow FFF, Electrical Asymmetrical Flow FFF, Centrifugal FFF, Thermal FFF and Gravitational SPLITT along with sophisticated detection systems such as e.g., UV-vis Spectroscopy (PN3200 UV), Multi-Angle Light Scattering (PN3600 MALS), Dynamic Light Scattering (e.g. Malvern Zetasizer), Intrinsic Viscosity (PN3300 Visco), Refractive Index (PN3100 RI) and Inductively-Coupled Plasma Mass Spectrometry (e.g. Agilent 7900 ICP-MS). With this modular approach that combines high-resolution fractionation with powerful detection; Postnova offers a comprehensive characterization platform that can be tailored to your needs to solve your analytical challenges.
