This lyophilized polystyrene standard, with a nominal molecular weight of 7,000,000 Daltons, is expertly designed for high-performance size exclusion chromatography (SEC) and gel permeation chromatography (GPC) calibration. It enables precise molecular weight determinations and polymer characterization in advanced research settings. Ideal for use in industries such as pharmaceuticals, polymers, and materials science, this standard allows for accurate instrument calibration, method validation, and system suitability assessments.

The polystyrene reference material demonstrates excellent solubility and stability in suitable organic solvents such as tetrahydrofuran (THF), ensuring reliable baseline performance and compatibility with a wide range of chromatographic columns and detectors. Researchers benefit from its high molecular weight, making it suitable for calibrating instruments when analyzing ultra-high molecular weight polymers and complex macromolecules.

This standard is fully compatible with Agilent’s renowned GPC and SEC instrument platforms, including the InfinityLab GPC/SEC systems, and can be used alongside other Agilent calibration standards to construct comprehensive calibration curves across a broad molecular weight range. In addition, it is well-matched for use with GPC software solutions for data analysis. The polystyrene standard meets stringent quality control specifications, delivering confidence in results and supporting rigorous analytical workflows.
