Designed for high-resolution separation of anionic compounds, this high-performance strong anion exchange column features a 70 angstrom pore size, 9.4 mm internal diameter, 250 mm length, and robust 5 micron particle size. Its chemically bonded quaternary ammonium functional groups enable efficient retention and selectivity for negatively charged analytes, including nucleotides, inorganic ions, and acidic biomolecules. This makes it ideal for ion-exchange chromatography applications in pharmaceutical, environmental, and biochemical research.

The precisely engineered silica matrix ensures consistent flow performance and reproducible results, supporting both analytical and preparative scale separations. Its compatibility with a wide range of HPLC and UHPLC systems, including Agilent 1260 Infinity II and 1290 Infinity II series instruments, allows seamless integration into existing laboratory workflows. This column is particularly useful for method development, quality control testing, and purification processes requiring robust separation of ionic species.

For enhanced productivity, users can pair it with other columns from the ZORBAX family, offering versatile selectivity options and scalable results. The durable hardware construction ensures chemical stability under diverse buffer and pH conditions, providing reliable performance over extended use and a wide range of sample types.
