Agilent’s polystyrene standard with a nominal molecular weight of 320000 Da is designed for demanding applications that require precise molecular weight calibration. This reference material is essential for qualitative and quantitative analysis in gel permeation chromatography (GPC) and size exclusion chromatography (SEC), providing accurate calibration across various molecular weight ranges. It is particularly suited for the characterization of polymers, quality control in manufacturing, and method development in academic or industrial polymer laboratories. The standard exhibits excellent solubility in commonly used organic solvents and delivers consistent, reproducible results.

This polystyrene standard is fully compatible with Agilent GPC and SEC systems, including detectors such as refractive index and multi-angle light scattering, as well as universal chromatographs. It also aligns with a broad range of chromatography columns and data analysis software, facilitating seamless integration into existing workflows. Researchers rely on this high-purity reference material for comparative studies, molecular weight distribution assessments, and to ensure regulatory compliance in product development. Its traceable certification and rigorous quality assurance make it a trusted choice for laboratories seeking accuracy in polymer molecular weight determination and reliable performance in polymer analytics.
