Field Flow Fractionation systems

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

  •     Eluent Pumps
  •      Multi-Angle Light Scattering Detector with 21 angles
  •     Refractive Index Detector
  •     ETC.

The most Advanced Flow FFF Platform for Separation of Proteins, Macromolecules and Nanoparticles


  • Professional Modular Platform

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.

  • Universal Flexible Separator

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.

  • Broad Separation Range

No size exclusion effect is observed, making HTFFF the ideal tool for the separation of large and ultra-large polymers or even nanoparticles.

  • Gentle Separation Conditions

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.

  • Patented FOCUS Technology

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.

  • Patented Cross Flow System

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.

  • Flexibility & Interfaceability

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.


  • AF2000 AT – Standard Ambient Temp Flow 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.

  • AF2000 MT – Advanced Mid Temp Flow FFF

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.

  • AF2000 HT – Toplevel High Temp Flow FFF
The AF2000 HT is a special temperature controlled toplevel Flow FFF system, which is ideal for the use in research, development and quality control of polyolefins and high temperature macromolecules in universities, public research institutions and industry.

AdvantagesUltrahigh resolution and very broad size range for polymers and particles

Field-Flow Fractionation is a family of separation techniques, comprising of various different sub-techniques. All these Field-Flow Fractionation versions utilize the same basic separation principle, but employ different force fields. Depending on the used separation field the technique is called Flow Field-Flow Fractionation, Sedimentation Field-Flow Fractionation, Thermal Field-Flow Fractionation or Split Flow Thin Cell Fractionation (SPLITT).Field-Flow Fractionation is providing fast, gentle and high resolution separations of any particulate matter from 1 nm up to 100 µm in a liquid medium. The sample is separated inside an open flow channel without the presence of any packing or stationary phase inside.

Unique Advantages
  • Ultrahigh resolution and very broad size range for polymers and particles
  • No shear forces and gentle separation especially for biomolecules
  • Direct molar mass and particle size determination without calibration standards
  • Temperature controlled system with patented reusable separation channel
  • No stationary phase or columns as spare part necessary
  • Analytes can be directly fractionated, collected and measure with additional on- and offline analytical methods as fluorescence, EM, AFM, etc.
