Designed for high-resolution anion-exchange chromatography, this strong anion-exchange (SAX) HPLC column features a 4.6 mm inner diameter, a length of 150 mm, and a particle size of 5 microns with 70 angstrom pore size. Its quaternary ammonium functionality provides robust retention and separation of acidic analytes including nucleotides, organic acids, and negatively charged biomolecules. Researchers in biopharmaceutical, environmental, and food analysis laboratories rely on this column for method development, routine analysis, and quality control of diverse anionic species.

The column's optimized silica support and uniform packing ensure reproducible performance, excellent peak shapes, and high loading capacity, enabling precise quantitation in complex sample matrices. It is engineered for compatibility with conventional HPLC systems from Agilent and other leading manufacturers, supporting both isocratic and gradient elution techniques.

Ideal applications include the separation of inorganic and organic anions, desalting, and analysis of charged biomolecules such as oligonucleotides and peptides. For extended utility, a wide selection of ZORBAX guard columns and compatible hardware accessories can be utilized, enhancing column lifetime and sample throughput. This product supports both routine and advanced analytical workflows, delivering reliable and reproducible results across a spectrum of research and testing environments.
