Chemical Composition Distribution

CRYSTAF


CRYSTAF instrument performs the Crystallization Analysis Fractionation technique to separate the polymer by its comonomer content. It is a fully automated instrument for fast measurement of Chemical Composition Distrinution (CCD) in Polyolefins. Polymer solution concentration is monitored by using infrared Detector IR4 of Polymer Char by carrying out a single temperature ramp (crystallation step).
