This high-purity polystyrene reference standard features a nominal molecular weight of 4500 Da and is designed for precise calibration and verification in gel permeation chromatography and size exclusion chromatography systems. It provides consistent and reliable performance to support molecular weight determinations across a range of polymer research and quality control applications. As a single-component standard, it enables accurate calibration curves, supports reproducibility in molecular weight measurements, and assists in system performance qualification.

Ideal for use in academic, industrial, and regulatory laboratories, this polystyrene standard is compatible with a wide variety of chromatographic instruments, including Agilent GPC SEC systems and detectors such as refractive index, light scattering, and viscometry. It can be used alone or as part of a broader polymer calibration suite to cover different molecular weight ranges. Closely related products, including other molecular weight polystyrene and polymethyl methacrylate standards, are available to tailor calibrations as required for specific polymer analyses. Each batch is rigorously characterized to ensure traceability and optimal solubility in common organic solvents, supporting robust, accurate, and repeatable chromatographic results for polymer science and quality assurance workflows.
