This high molecular weight polystyrene standard is engineered for precise calibration and verification of gel permeation chromatography (GPC) and size exclusion chromatography (SEC) systems. With a nominal weight average molecular weight (Mp) of 2,500,000 Daltons, it serves as an essential reference material for accurate determination of polymer molecular weights across a variety of research and industrial laboratories. The standard is particularly valuable for users seeking to characterize broad or high-end polymer molecular weight distributions in materials science, synthetic polymer development, and quality control environments.

Optimized for use with Agilent PLgel and other polystyrene-compatible GPC/SEC columns, this standard ensures reliable and reproducible results during system qualification and performance validation. It is supplied in a format suitable for direct dissolution and injection, minimizing preparation errors. Commonly employed in the calibration of detectors such as refractive index (RI), multi-angle light scattering (MALS), and viscometric detectors, it facilitates accurate data interpretation and cross-laboratory comparability. Compatible with a wide range of organic GPC solvents, this standard supports advanced applications in academic and industrial research, including polymer characterization, process monitoring, and formulation development.
