Polymer Characterization

Polymers are defined by the characteristics of their constituent monomer(s) and their microstructural arrangement. Infrared Spectroscopy coupled with a separation technique like Gel Permeation Chromatography (GPC) or Size Exclusion Chromatography (SEC) is well suited to determine the compositional and structural arrangement of polymers or copolymers. GPC-IR (GPC-FTIR or SEC-IR) instruments such as the DiscovIR are perfectly adapted to the needs of polymer chemists. It is adept at performing a wide range of applications such as formulation, deformulation of proprietary polymer blends, copolymer compositional drift or variation across the full Molecular Weight (MW) distribution, and process upsets.

These capabilities make the DiscovIR-GPC a proficient tool for meeting the specific demands of R&D and QA/QC laboratories. In addition, the DiscovIR-GPC is auto-sampler friendly and can function at high temperatures while offering the freedom to choose from many solvents for analysis.
