This advanced UHPLC column is designed for high-resolution, reproducible separations of large biomolecules, including peptides, intact proteins, and complex biotherapeutics. With a 300 angstrom pore size and stable diphenyl bonded phase, it enables excellent retention and selectivity for hydrophobic and aromatic analytes while maintaining peak integrity. The small 1.8 micron particle size ensures fast analysis and sharp peak shapes, making it suitable for both qualitative and quantitative workflows. Its robust silica matrix withstands high pressures and a range of pH conditions, supporting demanding analyses in proteomics, biopharmaceutical development, and quality control laboratories.

This column is fully compatible with Agilent InfinityLab and 1290 Infinity II systems, as well as other UHPLC platforms that accept 2.1 mm inner diameter columns. Common usage scenarios include peptide mapping, intact protein analysis, and the separation of post-translational modifications. It integrates seamlessly with related ZORBAX RRHD columns of varying chemistries, facilitating method development and optimization. Ideal for researchers requiring reproducible, high-throughput separations of complex biomolecules, this solution delivers consistent performance and reliability across a broad range of advanced analytical applications in life science and biopharma laboratories.
