This high-purity polystyrene reference material offers a nominal molecular weight of 25000 Da, making it ideal for advanced polymer characterization tasks. Specially optimized for use as a calibration standard, it enables precise and reliable molecular weight determination in gel permeation chromatography (GPC) and size exclusion chromatography (SEC) analyses. Its well-defined molecular weight properties support accurate calibration curves, facilitating reproducible qualitative and quantitative results in polymer research and quality control environments.

Designed for compatibility with Agilent and other leading GPC SEC systems, this polystyrene standard is well-suited for laboratories seeking robust performance for both routine and advanced analytical workflows. It is commonly utilized in the development, monitoring, and validation of industrial polymers, resins, elastomers, and synthetic materials, supporting applications such as molecular weight distribution analysis and batch-to-batch consistency evaluation. The reference material is also valuable in academic research for comparative studies and method development.

For enhanced calibration accuracy, this standard can be paired with additional polystyrene reference materials of varying molecular weights. It is delivered in a sealed vial to ensure sample integrity and long-term stability. Detailed certification documentation is included, supporting confidence and traceability in regulated and non-regulated laboratory settings.
