Agilent’s polystyrene standard with an approximate molecular weight of 56000 Daltons is designed for precise and reliable molecular weight calibration in gel permeation chromatography and size exclusion chromatography workflows. This linear polymer standard ensures accurate calibration of chromatographic systems, making it indispensable for laboratories analyzing polymer dispersity, molecular weight distribution, or conducting quality control of polymer-based products. Its high purity and narrow molecular weight distribution contribute to consistent and reproducible results across multiple runs.

Commonly used in material science, polymer chemistry, and industrial R and D settings, this standard supports critical research such as developing new polymeric materials, characterizing elastomers, and benchmarking instrument performance. It is compatible with a wide range of GPC and SEC systems, including Agilent PLgel, PL aquagel-OH, and other chromatographic columns designed for organic and aqueous solvent environments. The product’s excellent solubility in common organic solvents facilitates straightforward preparation and handling. For comprehensive polymer analysis and broader calibration, this standard can be used in conjunction with Agilent’s series of polystyrene standards of varying molecular weights to achieve detailed calibration curves tailored to specific application needs.
