HPLC Column, IEX WAX, 5um, 4.6mm ID x 100mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent IEX WAX is a weak anion exchange (WAX) HPLC stationary phase designed for the retention and separation of negatively charged compounds. Manufactured with high-purity silica and diethylaminopropyl functional groups, the stationary phase provides a positively charged surface within its functional pH range, delivering reliable anion exchange selectivity for acidic compounds and other anionic species. This chemistry has been widely utilized in ion exchange chromatography laboratories for many years and serves as an excellent alternative for many USP L9 methods.
67590-10P is a 100 mm x 4.6 mm ID analytical HPLC column packed with 5 µm WAX particles with a 100 Å pore size. The 100 mm length provides an excellent balance between analysis speed and chromatographic resolution, making it a popular choice for routine analytical methods, method development, and pharmaceutical testing. The 4.6 mm ID format is the industry standard for conventional HPLC systems and typically operates at approximately 1.0–2.0 mL/min, delivering robust performance and method transferability.
This weak anion exchange column is particularly useful for the analysis and purification of organic acids, pharmaceuticals, biomolecules, and other negatively charged compounds. The combination of selective WAX functionality, high-purity silica, and efficient 5 µm particles provides reproducible separations and dependable performance for challenging ion exchange applications requiring improved resolution compared to shorter column formats.
