This high molecular weight polymethyl methacrylate reference material is supplied in a broad molecular weight distribution with a nominal average molecular weight of 2,200,000 Da. It is optimized for use as a calibration standard in gel permeation chromatography (GPC) and size exclusion chromatography (SEC), supporting accurate and reproducible molecular weight determination of polymers. Researchers in polymer science, materials characterization, and quality control rely on this standard to validate instrument performance, calibrate detection systems, and ensure data reliability across a range of synthetic and natural polymer analyses.

Enhanced solubility in common organic solvents such as tetrahydrofuran facilitates rapid sample preparation and method development. The broad distribution profile enables the assessment of instrument resolution and detection capability for complex polymer samples. This PMMA reference is fully compatible with Agilent and other major GPC or SEC systems, including detectors such as refractive index, light scattering, and viscometry. It pairs effectively with Agilent PLgel and InfinityLab columns for robust calibration workflows. Researchers use this standard in academic, industrial, and manufacturing environments to support regulatory compliance, troubleshoot analytical methods, or benchmark new materials against established standards. Comprehensive certificate documentation accompanies the product for traceability and confidence in analytical results.
