Field Flow Fractionation (FFF) systems
Postnova is Inventor of Field-Flow Fractionation and has 30 years of experience in innovation and excellence of FFF-LS. Prof. Calvin Giddings from University Utah, Salt Lake City, USA invented and patented Field-Flow Fractionation in 1966.
Since then there has been lot of developments and various platforms have been developed for Field-Flow Fractionation.
The unique Postnova FFF Platform can be coupled to MALS, DLS, RI, UV and ICP-MS detectors
We have complete range of modules like detectors and eluent pumps which can be coupled with FFF
|seperation||upto 10E9 DA molar mass|
The new Postnova AF2000 MultiFlow FFF Series was invented to become the first professional modular Flow FFF platform available. It is completely integrated by the NovaFFF single software platform which runs the entire system from autosampler to detectors.
The AF2000 Series platform is based on the Flow FFF principle, using a crossflow field as driving force for the separation. The AF2000 MultiFlow can be easily used for separation of a broad range of different samples from the area of Biopharmaceuticals, Food-Agro-Cosmetics, Environmental, Chemicals and Nanotechnology.
No size exclusion effect is observed, making HTFFF the ideal tool for the separation of large and ultra-large polymers or even nanoparticles.
Because of the open channel and the absence of any stationary phase the separation can be performed under the absence of shear forces and stress to the macromolecule.
The AF2000 HT incorporates Postnova’s patented FOCUS technology, to ensure a continuous and stable detector flow at any time. The technology provides also a higher sample recovery, higher resolution and sensitivity.
Postnova is using a patented technology for generating the cross flow inside the FFF channel, based on a double syringe pump. This pump is controlled in a special unique way avoiding any pulsation.
The AF2000 MT series was developed to be used as Stand-Alone system or interfaced with existing HTGPC systems from various manufacturers. This gives the advantage that FFF and GPC can be performed using the same set or detectors, using the same temperature chamber for GPC and FFF.
The AF2000 AT is a non-temperature controlled economical Flow FFF which is ideal for the use in general level research in universities, companies and public scientific centers.
The AF2000 MT is a temperature controlled advanced Flow FFF system, which is ideal for the use in higher level research in university and public research institutions as well as professional research and commercial-industrial applications in the area of product development, manufacturing and quality control.
|Advantages||Ultrahigh resolution and very broad size range for polymers and particles|
