The CF2000 Series for high-resolution separation and fractionation of nanoparticles, from Postnova Analytics, has won the GIT Innovations Award 2012 in the category ‘Analytical Instrumentation and Software’. The Postnova team are the inventors of the Field-Flow Fractionation (FFF) technique, and developed the CF2000 to be the first Centrifugal FFF system for routine use.
Importantly, by using a centrifugal field as the controlling force for the separation, particles are separated by Dynamic Diffusion on the basis of size and density. This novel approach allows discrimination of materials that have the same particle size but different densities.The CF2000 has a wide operation range and is able to separate smaller species, such as proteins and polymers, from larger particles in one run with high resolution. The system is ideal for nanoparticles and works up into the microparticle size range too.
