CFC Analysis Overview

Cross-fractionation analysis is performed by a Polymer Char’s CFC Instrument, developed to measure the Bivariate Distribution by analytical TREF or TGIC fractionation and subsequent online GPC analysis of the fractions, obtaining 3D plots as well as the recovered TREF or TGIC and GPC profiles, in a single analysis by using an infrared detector (IR5 MCT).

The polymer is fractionated by crystallinity using a TREF or TGIC analysis at increasing temperature steps, that can be taken at any temperature (including subambient), and fractions are automatically injected into GPC columns.
