Crystallization Elution Fractionation (CEF)
CEF is a new technique for the fast measurement of the chemical composition distribution in polyolefins. It combines crystallization analysis fractionation and temperature rising elution fractionation for superior resolution and provides a concentration versus temperature curve.
- Combinable with a viscometer or IR detector
- Excellent reproducibility
- Subambient (-20°operation for low crystallinity samples possible)
- Suitable for a range of samples including LDPE, HDPE, E-P copolymers and any semicrystalline polymer soluble in TCB or DCB
