This high molecular weight dextran standard offers a nominal molecular weight of 2,000,000 Da, making it ideal for the calibration and performance verification of size exclusion chromatography (SEC) systems. It is specifically designed for accurate molecular weight determinations in polysaccharide analysis, quality control of biopharmaceuticals, and advanced polymer characterization. With a broad molecular weight distribution, this standard enables reliable calibration across a wide range of elution volumes, ensuring precise size separation and reproducible results.

Common research applications include system suitability testing, validation of chromatography columns, and establishing reference profiles in biopolymer analysis. This dextran standard is fully compatible with Agilent SEC instrumentation, including the InfinityLab and 1260 Infinity II platforms, as well as a wide range of rival chromatographic systems and detectors such as refractive index and light scattering.

For comprehensive molecular weight distribution studies, it can be used in conjunction with other dextran or pullulan standards available from Agilent. Researchers benefit from its high purity and lot-to-lot consistency, facilitating robust method development and regulatory compliance. Each unit is supplied with a certificate of analysis to support data integrity and traceability in regulated laboratory environments.
