Description
Temperature Rising Elution Fractionation has been the most comprehensive technique for the characterization of the Chemical Composition Distribution (CCD) in polyolefins, and Polymer Char’s TREF is the first fully automated apparatus implementing this technique.
TREF can be converted into a CRYSTAF-TREF combined system capable of running both techniques by using the same hardware. Each technique can provide complementary information on the CCD in some complex resins.
Features - Full automation of the TREF techniques to measure the CCD
- 5 samples can be analyzed sequentially with no supervision required, with an analysis time of 6 hours per sample.
- Possibility of adding other detectors like Viscometer or Light Scattering.
- Easy convertible into a CRYSTAF-TREF apparatus.
- Possibility of subambient operation (down to -20ºC) for low crystallinity samples.
