Agilent offers a specialized dextran standard with a nominal molecular weight of 1,500,000 Da designed for advanced analytical and research applications. This high-molecular-weight polysaccharide is ideal for calibrating and validating size exclusion chromatography (SEC) and gel permeation chromatography (GPC) systems, enabling precise molecular weight determination and characterization of macromolecules. The broad distribution profile makes it suitable for method development and performance checks in biopharmaceutical analysis, polymer research, and quality control laboratories.

Researchers use this dextran standard to assess column performance, optimize separation conditions, and ensure reproducibility in the measurement of proteins, peptides, and synthetic polymers. It is compatible with a wide range of Agilent liquid chromatography instruments, including HPLC and UHPLC platforms, as well as other leading SEC or GPC systems. When paired with Agilent chromatography columns such as the AdvanceBio SEC or PLgel series, users achieve reliable and consistent results. This standard is also useful when verifying the accuracy and linearity of multi-angle light scattering (MALS) or refractive index (RI) detectors. Engineered for stability and performance, it is an essential tool for laboratories requiring robust quality standards and accurate molecular weight calibration.
