This highly purified polystyrene polymer standard features a nominal molecular weight of 1800000 Da, making it ideally suited for advanced molecular characterization techniques. Designed for use in gel permeation chromatography GPC and size exclusion chromatography SEC systems, this high molecular weight standard enables accurate calibration and qualification of chromatographic columns, detectors, and related equipment. It provides excellent solubility and stability in typical organic solvents used for polymer analysis, such as tetrahydrofuran and chloroform.

Researchers in the fields of polymer science, quality control, and materials development utilize this standard to validate molecular weight measurements, ensure method reproducibility, and assess column performance. Its well-defined molecular distribution supports precise determination of molecular weight averages and distribution parameters, facilitating the development of synthetic polymers and the comparison of batch-to-batch consistency. The product is fully compatible with Agilent and other major analytical GPC SEC systems, as well as multi-angle light scattering MALS, refractive index RI, and viscometric detectors. It is also complementary to Agilent's complete portfolio of polymer standards, allowing users to cover a broad range of molecular weights for comprehensive instrument calibration. This polystyrene standard is supplied with a certificate of analysis detailing its molecular characteristics for traceable, reliable results.
