TREF
Temperature Rising Elution Fractionation is the most comprehensive technique for the characterization of the Chemical Composition Distribution (CCD) in Polyolefins and Polymer Char’s TREF is the first automated analytical instrument that performs this technique.
The virtual instrumentation software controls the full process, so no manpower is required. Samples are put into the vessels and the instrument performs the solvent filling, dissolution, column loading, and temperature cycles combined with pump flow control. At the end, vessels and lines are cleaned and ready to analyze more samples.
