The ZORBAX 300SB-C18 Guard Cartridge is a 5 micron, 0.5 x 35 mm column designed to protect and extend the life of analytical columns during high-performance liquid chromatography applications. Engineered with StableBond C18 reversed-phase chemistry, this guard cartridge is ideal for safeguarding columns from particulates and strongly retained contaminants, helping maintain peak performance and reproducibility in complex sample analysis.

Optimal for protein and peptide separations, it is especially well-suited for reversed-phase chromatography involving large biomolecules. Common research applications include proteomics, pharmaceutical compound analysis, peptide mapping, and biotherapeutic characterization. The 300 Angstrom pore size allows efficient separation of larger molecules without compromising resolution or flow rates.

Compatible with Agilent ZORBAX 300SB-C18 analytical columns and other Agilent HPLC systems, this guard cartridge seamlessly integrates into workflows for added column protection. It is also suitable for use with a range of HPLC instruments requiring secure and consistent sample analysis, reducing downtime due to column fouling.

For laboratories seeking reliable protection for sensitive and high-value columns in demanding analytical environments, this guard cartridge delivers consistent performance and enhances overall system longevity, supporting rigorous and reproducible chromatographic workflows.
