Agilent’s high-purity polystyrene standard with a nominal molecular weight of 7,000 daltons is specifically engineered for precise calibration and performance verification of gel permeation chromatography GPC and size exclusion chromatography SEC systems. This monodisperse standard provides accurate and reliable molecular weight references, supporting consistent and reproducible chromatographic analyses across a wide range of polymer research and quality control applications. Typical usage includes the calibration of chromatographic columns, validation of system performance, and the establishment of calibration curves for molecular weight distribution determinations in laboratory and industrial environments.

Designed for compatibility with Agilent’s suite of GPC SEC instruments and detectors, including refractive index and light scattering detectors, this standard can also be used with a variety of third-party chromatography setups. Its high level of purity and defined molecular weight make it ideal for users assessing polymer synthesis, degradation, or composition. The polystyrene matrix ensures chemical stability and reproducibility in both aqueous and organic solvent systems. For laboratories conducting analytical method development, validation, and regulatory compliance testing, this molecular weight standard offers traceable and dependable performance. Complementary molecular weight standards are available to extend calibration ranges and meet diverse analytical requirements.
