Model 350 high-temperature gel permeation chromatography (HT-GPC)

The Model 350 high-temperature gel permeation chromatography (HT-GPC) system is specifically designed for the characterization of polyolefins and other synthetic polymers that are soluble only at elevated temperatures. It provides absolute molecular weight without extrapolation or correction, as well as molecular size (Rg and Rh to less than 1 nm) and intrinsic viscosity. It also gives information on branching, structure and aggregation in a single GPC/SEC (size exclusion chromatography) experiment. The system may be configured with an infrared (IR)detector for short-chain branching analysis or an ultra­violet/visible (UV/VIS) detector for copolymer compositional analysis. It is designed in a modular format and features automated sample preparation and delivery, self-cleaning inline sample filtration, and a detector module that is easily removed for routine maintenance.
