Designed for high-performance protection of analytical columns, this guard cartridge provides robust sample cleanup in demanding bioseparations. Featuring a 300 Angstrom pore size and C8 hydrophobic bonding, it enables efficient retention and separation of moderately hydrophobic biomolecules such as peptides, small proteins, and complex biological samples. With a 2.1 x 12.5 mm format and 5 micron particle size, each cartridge preserves sample integrity while minimizing band broadening and back pressure, supporting reproducible and high-resolution chromatographic results.

Engineered for compatibility with UHPLC and HPLC systems, this guard cartridge is ideally paired with longer analytical columns utilizing the same ZORBAX StableBond 300 C8 stationary phase. Researchers in proteomics, drug development, and biomolecule characterization can rely on its stable siloxane bonding for reliable performance under low and medium pH conditions. The tool-free design streamlines cartridge replacement, minimizing instrument downtime during high-throughput workflows.

Packaged in sets of four, these cartridges extend the lifetime of primary columns and reduce maintenance costs in labs focused on peptide mapping, protein quantitation, and pharmaceutical quality control. Supporting integration with Agilent systems and accessories, this guard cartridge complements a comprehensive portfolio of ZORBAX columns for superior analytical flexibility.
