The Agilent ZORBAX StableBond 300 C8 column is engineered for high-performance liquid chromatography (HPLC) analysis of biomolecules, especially peptides, small proteins, and other moderately hydrophobic compounds. Featuring a 2.1 mm inner diameter and 50 mm length with 3.5 micron particle size, this column delivers efficient resolution and robust performance under a wide range of high and low pH mobile phase conditions. The 300 angstrom pore size ensures excellent accessibility for larger analytes, making it highly suitable for peptide mapping and protein characterization workflows in pharmaceutical, biotechnology, and academic research laboratories. The dense C8 bonding offers optimal retention for analytes requiring moderate hydrophobic interaction, providing balanced retention and fast run times. Compatible with all major HPLC and UHPLC systems, this column integrates seamlessly into existing workflows and is fully supported by Agilent’s selection of guard columns and accessories. It is frequently used in method development, quality control, and routine screening applications. Its stable silica-based chemistry ensures long column lifetime and batch-to-batch reproducibility, supporting reliable and consistent results across multiple analytical runs. Researchers can achieve reproducible separations with demanding biological samples, enhancing data integrity in proteomics and pharmaceutical R&D.
