This high-performance guard column is designed to protect and extend the lifetime of analytical size exclusion chromatography (SEC) columns during the analysis of proteins, peptides, and other biomolecules. Featuring a 150 angstrom pore size, 4.6 mm internal diameter, and 50 mm length with 5 micron particle size, it efficiently removes particulates and sample contaminants that can degrade column performance. Ideal for routine and demanding SEC applications in pharmaceutical, biotechnology, and academic environments, it ensures reliable separation of biomolecules under native conditions, critical for accurate molecular weight determination and aggregate analysis. Compatible with Agilent’s Bio SEC-5 analytical columns, it integrates seamlessly with Agilent 1260 Infinity and 1290 Infinity series LC systems, as well as other major HPLC platforms. It is particularly suited as a guard for columns analyzing monoclonal antibodies, fusion proteins, and other complex biomolecules, helping maintain optimal peak shape and reproducibility. The robust silica-based packing and precision engineering deliver consistent performance and column integrity over repeated use. This accessory provides a cost-effective solution for safeguarding main analytical columns, thus enhancing productivity and minimizing instrument downtime in high-throughput laboratory workflows.
