The Agilent Bio SEC-5 2000Å guard column is designed to enhance the lifetime and performance of main analytical columns in size exclusion chromatography applications, particularly those involving the analysis of large biomolecules such as monoclonal antibodies, protein aggregates, and other biotherapeutics. With a pore size of 2000 angstroms, a 7.8 x 50 mm format, and a 5 µm particle size, this guard column provides optimal protection against sample particulates and contaminants, ensuring consistent and reliable chromatographic results. It is especially suitable for use in protein characterization, quality control of biopharmaceuticals, and high-resolution aggregate analysis in research or industrial settings. The column is compatible with Agilent's full range of Bio SEC-5 analytical columns and works seamlessly with HPLC and UHPLC systems, including those from Agilent InfinityLab and 1260/1290 series platforms. By matching the stationary phase properties of the primary column, it preserves selectivity and efficiency while extending column lifetimes and reducing maintenance downtime. Recommended for laboratories requiring robust performance and high reproducibility in size exclusion separations. Integration with additional reference standards and bio-inert system components further maximizes analytical reliability for sensitive biomolecule workflows.
