CEF
Crystallization Elution Fractionation (CEF) is a new approach to measure the Chemical Composition Distribution (CCD) in Polyolefins by combining CRYSTAF and TREF separation mechanism. It is of special interest for high speed analysis.
CEF instrument is a simple and reliable instrument, requiring only an injection valve, a packed column, a pump and IR detector. The autosampler attached to CEF oven deals with samples dissolution in vials of 10 or 20 ml. The instrument has the capability to analyse 42 samples a day with no supervision required
