Description
Crystallization Elution Fractionation (CEF) is a new approach for measuring Chemical Composition Distribution (CCD) in polyolefins that combines the separation mechanisms of CRYSTAF and TREF. The instrument includes the capability of performing TREF and TGIC* techniques.
The instrument can analyze up to 42 or 66 samples a day with disposable glass vials of 10 or 20 mL. The virtual instrumentation software controls the full process; therefore, no manpower is required.
The concentration of the sample is measured by an Infrared detector, which also provides information about its comonomer content. More information on molar mass composition interdependence can also be obtained by adding a Viscometer detector. Optionally, the TREF column can be replaced by a TGIC* column in order to separate by adsorption and reach the composition range of elastomer resins.
Features - Useful technique for the identification of components in Post Consumer Recyclates (PCR), PP-PE blends, and other recycled polymers
- Fully automated CEF, TREF and TGIC* techniques (CCD measurement).
- No manpower required.
- No handling of solvents.
- Low solvent consumption.
- Automated rinsing at the end of the analysis.
- Subambient operation (down to -20ºC) for low crystallinity samples.
- 42 or 66 samples can be analyzed sequentially and automatically with analysis time as short as 30 minutes per sample for high throughput analysis or as long as desired for high resolution analysis.
- Infrared Detection for outstanding sensitivity in concentration and composition, and carbonyls capability.
- Possibility of adding a Viscometer detector.
- Excellent reproducibility.
- Possibility of performing TGIC* by hanging the column.
