Polymer Char is devoted to the development of state-of-art instrumentation for Polyolefin Analysis. They offers the broadest and most modern range of instruments and services for structural characterization of polyolefins such as Gel Permeations Chromatography (GPC/SEC), Chemical Composition Distribution, Bivariate Distribution, High Temperature HPLC, Soluble Fraction determination, Quality Control, Intrinsic Viscosity measurement, Preparative Fractionation or Infrared Detection.

CRYSTAF is a fully automated instrument intended for the fast measurement of the Chemical Composition Distrinution (CCD) in Polyolefins.
