TREF Analysis Additional Detectors

Other detectors can be used in Polymer Char’s TREF Instrument in line with the infrared detector:

Composition and C=O content

A composition sensor or a carbonyl sensor can be placed in the infrared detector IR4 to measure the number of CH3/1000C or the CO content in EVA type resins and others correspondingly. Composition and concentration are measured simultaneously.


By connecting a capillary viscometer to a TREF, the bulk Intrinsic Viscosity (IV) is measured, and therefore results on the Molar Mass tendency versus the CCD curve are obtained.
