Agilent’s polystyrene standard with a nominal molecular weight of 4,000 Da delivers high reliability for precise polymer characterization and quality control. This linear polymer standard is expertly engineered for use in gel permeation chromatography (GPC) and size exclusion chromatography (SEC), providing accurate calibration of molecular weight with narrow molecular weight distribution. The product is especially suitable for researchers and laboratories conducting polymer analysis, molecular weight determination, and method validation in both academic and industrial settings. Its well-defined properties support applications in plastics research, quality assurance, and development of new polymeric materials. This standard is fully compatible with Agilent GPC and SEC instruments, including the 1260 Infinity II and 1290 Infinity II systems, and is also suitable for use with other leading chromatography platforms. Researchers can rely on this product for performance consistency when developing and comparing methods or evaluating the performance of columns and detectors. Offering precise traceability and consistent batch quality, this standard can be paired with other molecular weight polystyrene standards and calibration kits for advanced multi-point calibration curves. Supplied in an easy-to-dissolve form, it allows rapid preparation in common organic solvents, streamlining laboratory workflows and ensuring reproducible analytical results.
