This polystyrene reference standard has a nominal molecular weight of 18000 Daltons, making it ideal for precise calibration in gel permeation chromatography (GPC) and size exclusion chromatography (SEC) analyses. Its well-characterized molecular properties enable reliable determination of molecular weight distributions in polymers, ensuring consistent and reproducible results across analytical workflows. Commonly employed in academic and industrial laboratories, this standard is suitable for verifying the performance of chromatographic columns and systems, as well as for establishing calibration curves for polymer analysis.

Optimized for compatibility with Agilent GPC and SEC instruments, this reference material seamlessly integrates into multi-detector setups, including systems equipped with refractive index, light scattering, or viscometry detectors. It can also be utilized alongside other molecular weight standards to construct wide-ranging calibration sets for various polymer types. Laboratories engaged in quality control, material development, or method validation will benefit from the standard's high purity and batch-to-batch consistency. This product is part of Agilent’s comprehensive portfolio of polymer standards, supporting both routine polymer characterization and advanced research needs in polymer science and materials engineering.
