This polystyrene standard features a nominal weight-average molecular weight of 6,500,000 Daltons, ideal for advanced gel permeation chromatography GPC and size exclusion chromatography SEC applications. It is designed to enable accurate calibration of molecular weight distribution in high molecular weight polymer analysis. The standard is supplied in a precisely measured quantity with tight molecular weight distribution, ensuring reproducibility and reliability of results in quality control, research, and development settings.

Its high molecular weight makes it particularly suitable for laboratories analyzing ultra-high molecular weight polymers, assessing polymerization processes, or developing new polymeric materials. This standard is compatible with Agilent GPC SEC systems and detectors, including multi-angle light scattering MALS and refractive index detectors, as well as other common chromatography instruments.

Researchers in polymer science, material science, and industrial quality assurance use this product to calibrate columns, validate analytical methods, and assess sample heterogeneity. It also serves as a valuable reference when comparing unknowns or optimizing separation conditions for challenging polymer samples. Comprehensive documentation and traceability support compliance with regulatory and quality standards, fostering confidence in demanding analytical environments. Matching products with different nominal molecular weights are available for robust calibration curves and system suitability testing.
