Smithers performs gel permeation chromatography, commonly known as GPC testing, and size exclusion chromatography (SEC) for polymer molecular weight characterization.The molecular weight and structure of a polymer influences processing behavior and physical properties of the finished product....
IR6 is the latest infrared detector developed by Polymer Char. It has superior performance and sensitivity and the additional capability of measuring carbonyl group in the band of 1740 cm-1. The IR6 detector is recommended for users that want to analyze EVA, EBA, and other polyolefins which ...
Where a polymer'send-use application requires precision performance or endurance under harshconditions, the need for polymer characterization is particularly acute.Because GPC fulfills these needs better than any other single technique, it hasbecome an extremely valuable tool for materials characterization ...
GPC-FTIR Interfacing chromatographic methods with other analytical techniques can significantly increase the amount of information available for polymer characterization. Agilent offers two innovative interfaces to couple gel permeation chromatography (GPC) with Fourier transform infrared spectroscopy (FTIR), ...
Aqueous GPC analysis brings a whole newset of challenges to the polymer characterization chemist. Most conventional,high performance packings for aqueous GPC analysis are prepared fromhydrophilic methacrylate gels, with residual carboxylate groups, giving thecolumn chemistry an overall anionic charge. When ...
distribution curves which are needed to characterize a polymer with regard to differences in properties. GPC-SEC is mainly used for samples with a molecular weight above 2000 although it is also in use for oligomer separations. There is no upper limit in the molecular weight, even polymer ...
As polymer characterization chemists strive to learn as much as they can about their samples, other detection options are considered. As we move into the world of "advanced" detection for GPC analysis, we begin to consider the molecular weight sensitive detectors such as viscometry and light sca...
Craven Arms, UK Application Note Abstract The Agilent 1260 Infinity Multi-Detector GPC/SEC System is a powerful tool for polymer characterization. The signals from a concentration sensitive detector such as refractive index (RI) or ultra-violet (UV) coupled with light scattering and viscometry can...
Gel Permeation Chromatography (GPC) is an analytical technique for the characterization of a wide variety of polymers or other macromolecules in a mixture. In GPC, a solution of dissolved sample is passed through a column with a controlled-porosity packing, typically a polymeric porous gel (...
