This polystyrene standard offers a nominal molecular weight of 2,500,000 daltons, enabling precise calibration for gel permeation chromatography (GPC) and size exclusion chromatography (SEC) systems. Designed for high reliability and consistency, it is ideally suited for molecular weight determination and characterization of polymers in research and quality control environments. The high molecular weight facilitates accurate calibration of the upper end of the chromatographic range, supporting the analysis of ultra-high molecular weight polymers, plastics, and resins. Compatible with a wide array of Agilent GPC and SEC instruments, as well as other leading chromatography systems, this standard ensures broad applicability across academic, industrial, and regulatory laboratories. Its well-defined narrow molecular weight distribution results in dependable and reproducible performance, assisting researchers in achieving robust method validation and data comparability. This standard is supplied in a high-purity, low-dust format, minimizing sample contamination and column fouling during use. For laboratories conducting polymer characterization, batch-to-batch QC, or developing new polymeric materials, this standard integrates seamlessly with Agilent’s range of certified GPC columns and sample preparation solutions. The product’s traceability and detailed certification further enhance data confidence, making it an essential calibration solution for advanced polymer analysis.
