Polymer Characterization, S.A products

GPC-IR is a High Temperature Gel Permeation Chromatograph or Size Exclusion Chromatograph (GPC/SEC) dedicated to Polyolefin analysis with an infrared detector as primary detector. Two options are available; IR4, with sensors for concentration and composition measurement of short chain branching or carbonyls, or IR5 MCT, for composition measurement of short chain branching with a high sensitivity thanks to an MCT sensor thermoelectrically cooled, with no need of liquid nitrogen. Both detectors can be integrated into the system with no transfer line, achieving the best sensitivity without compromising the chromatography quality. Triple detector configuration can be completed by a four capillary bridge built-in viscometer and a Multi-Angle Light Scattering (DAWN® HELEOS™ II 8 or 18 angle of Wyatt Technology).

The Data Unit 200 is an A/D interface to link any existing GPC instrument with Polymer Char GPC One Software modules.

CRYSTAF is a fully automated instrument intended for the fast measurement of the Chemical Composition Distribution (CCD) in Polyolefins. CRYSTAF instrument performs the Crystallization Analysis Fractionation technique to separate the polymer by its comonomer content. The process is done in a single temperature ramp (crystallization step), while the polymer solution concentration is monitored by using the Infrared Detector IR4 of Polymer Char.

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 fully automated analytical instrument that performs this technique.
