Postnova Thermal Field-Flow Fractionation TF2000 system

Ideal for complex, broad-distributed, cross-linked or high molar mass polymers, starches, gel-like materials, latexes, or mixtures of polymers and nanoparticles

The Postnova TF2000 Thermal FFF system can efficiently separate and characterize polymers and particles. The system is able to separate simultaneously polymers and particles without the limitations associated with GPC/SEC. The separation takes place according to molecular weight AND chemical composition, thus making the TF2000 Series the ideal choice for co-polymer separation. The system has a large separation range and can fractionate polymers as low as 10 kDa up to 100 MDa including microgels and nanoparticles. The separation itself is very gentle and ruled by thermal diffusion and Brownian motion in a laminar flow channel without using any stationary phase as in chromatography.

The system can be coupled with different standard detectors such as Light Scattering (MALS and DLS), RI, UV, etc.
