The Postnova TF2000 is an advanced thermal field flow fractionation (TF3) system that provides a highly efficient method of separating and characterising complex polymer samples such as natural or synthetic rubbers, starches and paints from approximately 10 kDa up to 100 MDa and more in organic and aqueous solvents.

Postnova Analytics reports on exciting advances in the analysis of plasma proteins using a hyphenated system that couples asymmetric flow Field-Flow Fractionation (AF4) and inductively coupled plasma-mass spectrometry (ICP-MS). In a new application study researchers show how an AF4-ICP-MS system is able to obtain valuable information on the multi-element speciation and absolute molecular mass of human plasma proteins such as Albumin and Transferrin.
