CRSTAF and TREF techniques are intended to measure the Chemical Composition Distribution in Polyolefins; CRYSTAF analyses it in the crystallization cycle and TREF in the dissolution cycle. 

The analysis of complex PP-PE combination has been shown to require both TREF and CRYSTAF to unequivocally characterize unknown samples due to the differences in the undercooling between both resins. Such a case is the analysis of samples containing both HDPE and Ethylene-Propylene copolymer (EP) for instance.

  • Benchtop instrument with the possibility of performing CRYSTAF or TREF techniques.
  • Fully automated processes, from the sample preparation up to the final cleaning.
  • No manpower and no solvents handling.
  • Possibility of analyzing up to 5 samples with no supervision required.
  • Low solvent consumption.
  • Infrared Detector IR4 incorporated, with the possibility of adding a composition sensor for methyls or carbonyls measurement.
  • Possibility of adding a Viscometer detector in TREF mode.
  • Possibility of subambient capability (down to -20ºC) for low crystallinity samples.
  • Virtual Instrumentation software with whole control of the instrument process, storage of all the detectors signals and monitoring of the sensors system.
  • Possibility of remote control capability for fast diagnosis and support from Polymer Char Service Center.
