CEF Insturment,42 Samples, Polymer Characterization, S.A., (CAT#: STEM-LE-0939-LC)

Crystal elution fractionation (CEF) is a new method for measuring the chemical composition distribution (CCD) in polyolefins by combining the separation mechanism of CRYSTAF and TREF. The instrument has the ability to perform TREF and TGIC technologies. CEF is a simple and reliable device that requires an injection valve, packed column, pump and IR detector. The autosampler connected to the CEF oven is responsible for dissolving the sample in 10 or 20 mL vials. The instrument can analyze up to 50 samples per day using disposable glass bottles.

Type:Crystallization Elution Fractionation
Detector(s):Infrared Detector IR4 and IR5 MCT, Viscometer
Number of Samples:42 samples

Fully automatic CEF, TREF and TGIC technology (CCD measurement).
No manpower is required.
Do not handle solvents.
Low solvent consumption.
Automatic flushing at the end of the analysis.
Ambient operating temperature for low crystallinity samples (down to -20°C).
42 samples can be analyzed automatically in sequence. For high-throughput analysis, the analysis time of each sample is as short as 30 minutes, while for high-resolution analysis, it takes a long time.
Easy to interchange infrared detector; IR5 MCT has excellent concentration and composition sensitivity, IR4 has carbonyl capability.
Possibility to add viscometer detector.
Excellent reproducibility.
