This high-performance strong anion exchange (SAX) HPLC column is engineered for reliable separation of acidic biomolecules, such as nucleotides, peptides, and proteins, in complex analytical samples. Featuring a 70 Angstrom pore size, 4.6 mm internal diameter, and 250 mm column length, with 5 micron particle size, it provides excellent resolution and efficiency for demanding chromatographic applications. The optimized SAX chemistry ensures strong retention and sharp peak shapes for anionic species under a wide pH range, making this column ideal for the analysis of oligonucleotides, phosphopeptides, and other negatively charged analytes.

Designed for compatibility with Agilent 1100, 1200, and Infinity HPLC systems as well as most standard liquid chromatography instruments, this column is suitable for research laboratories focusing on biopharmaceuticals, proteomics, and genomics. It is also well-suited for regulatory environments requiring consistent performance and reproducibility. The ZORBAX family provides a robust platform for method development and routine quality control analyses. For further optimization of analytical workflows, this column can be paired with other ZORBAX phases for multi-dimensional separations or used with matching guard columns to extend column lifetime.
