Chemical Composition Distribution

CEF


An advanced approach of measuring Chemical Composition Distribution (CCD) by Crystallization Elution Fractionation (CEF) in Polyolefin. It is a high throughput analysis with capability of measuring 42 samples a day.

IR 4 or IR 5 MCT infrared detector is used to measure concentration and comonomer content of sample. Viscometer detector can be added to CEF to obtain more information.
