Agilent’s high molecular weight polystyrene is a well-characterized polymer standard with a nominal molecular weight of 5,000,000 Daltons. This product is designed for use as a reference material in molecular weight determination and calibration of gel permeation chromatography GPC and size exclusion chromatography SEC systems. Its broad application includes quality control, method development, and performance verification in both research and industrial laboratories working with synthetic polymers. Suitable for use in defining system resolution and validating the separation range, this polystyrene standard ensures the accuracy and reliability of polymer analysis.

Ideal for laboratories utilizing Agilent and other major chromatography platforms, it is compatible with a wide variety of GPC and SEC instruments equipped with refractive index, light scattering, or viscometric detection. This standard can be used alongside other molecular weight standards to generate calibration curves for the precise characterization of unknown polymer samples. It supports compliance with standard test methods such as ASTM and ISO. Agilent’s portfolio also includes standards covering a spectrum of molecular weights, enabling comprehensive system qualification. Supplied in a well-sealed container to ensure stability and integrity, this product is an essential tool for consistent and reproducible polymer analysis.
