HT-GPC System Analyzes Soluble Polymers at Elevated Temperatures

The model 350 high temperature GPC (HT-GPC) system is an advanced detector used for the characterization of polyolefins and other synthetic polymers that are soluble only at elevated temperatures. The system provides absolute molecular weight without extrapolation or correction, molecular size (Rg and Rh to less than 1 nm) and intrinsic viscosity as well as information on branching, structure and aggregation in a single GPC/SEC experiment. The system can also be configured with an IR detector for short-chain branching analysis or a UV-Vis detector for copolymer compositional analysis. Additional features include a high temperature triple detector array (HT-TDA), an automated sample preparation and delivery system, a pulseless isocratic pump, degasser and omniSEC GPC software. The system combines low angle light scattering with viscometry and concentration for complete macromolecular characterization. All detectors reside within a temperature-controlled oven compartment (30 C to 175 C), which has space for four analytical GPC columns.
