This high-purity polystyrene with a nominal molecular weight of 162 Daltons is specifically formulated for precise size calibration in gel permeation chromatography and size exclusion chromatography systems. Its well-defined molecular weight makes it an essential reference standard for laboratories seeking to validate system performance, verify chromatographic resolution, or establish accurate molecular weight calibration curves. Researchers working in polymer chemistry, materials science, or quality assurance frequently use this standard to benchmark instrument performance and assess sample molecular distribution in both routine and advanced analytical workflows.

The product is compatible with Agilent GPC SEC systems, including both refractive index and multi-angle light scattering detectors, and integrates seamlessly into workflows using a broad range of organic-phase chromatographic solvents. Its stability and consistent performance ensure reliable results when characterizing low molecular weight compounds or fine polymers. This polystyrene standard is ideal for use alongside Agilent’s selection of GPC columns and calibration mixes, and can also support method validation, troubleshooting, and system suitability testing. The high batch-to-batch reproducibility ensures data integrity and traceability, making this standard a valuable component for laboratories where precise molecular weight determination and quality control are critical.
