This high-performance polystyrene sulfonate standard is designed for precise determination of molecular weight distributions in synthetic polymer analysis. With a nominal molecular weight of 500,000 Daltons and broad molecular weight characteristics, it is ideally suited for calibration and validation of gel permeation chromatography GPC and size exclusion chromatography SEC systems. Researchers can employ this standard to establish and verify column performance, assess system suitability, or benchmark the accuracy of molecular weight measurements in routine quality control or advanced polymer research.

Optimized for compatibility with Agilent and third-party chromatographic instruments, this standard ensures reliable and reproducible results across a range of aqueous or organic solvent systems. It is particularly relevant in environments requiring rigorous calibration protocols, such as academic research laboratories, industrial polymer development, and regulated quality assurance settings. When used alongside Agilent GPC columns, detectors, and mobile phase solutions, it delivers enhanced accuracy in polymer characterization workflows. Packaged for long-term stability, this polystyrene sulfonate reference material is an essential component for laboratories engaged in polymer science, materials research, and performance testing of chromatographic systems. Related standards with varying molecular weights are available to support the development of comprehensive calibration curves.
