This high-molecular-weight dextran standard is designed for precise molecular weight calibration and characterization tasks in gel permeation chromatography (GPC) and size exclusion chromatography (SEC) applications. With a nominal molecular weight of 2,000,000 Daltons, this broad standard is ideal for determining column performance, verifying system suitability, and assessing separation ranges for polymers and biopolymers. Its consistent performance makes it suitable for research in biochemistry, polymer science, and pharmaceutical development, particularly in studies requiring accurate quantification of very high molecular weight compounds.

The dextran standard is fully compatible with Agilent GPC-SEC instruments, including detectors such as refractive index, light scattering, and viscometry modules. It supports method development and validation for both aqueous and organic GPC-SEC systems and is often used alongside other molecular weight standards to construct calibration curves across an extended mass range. The product supports quality control, batch comparison, and stability testing in both academic and industrial laboratories. For best results, it may be paired with recommended Agilent GPC/SEC columns and system-compatible sample preparation protocols. This standard provides robust, reproducible calibration, enhancing the reliability and accuracy of your macromolecular analyses.
