HPLC Column, IEX WAX, 5um, 4.6mm ID x 150mm 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 using 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 analytes. This chemistry has been widely used in HPLC laboratories for many years and serves as an excellent alternative for many USP L9 methods.
67590-15P is a 150 mm x 4.6 mm ID analytical HPLC column packed with 5 µm WAX particles with a 100 Å pore size. The 150 mm length provides increased resolving power and peak capacity compared to shorter columns, making it ideal for applications requiring enhanced separation of closely related compounds, impurity profiling, and more demanding ion exchange analyses. 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, providing robust and reproducible chromatographic performance.
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 delivers excellent chromatographic performance for challenging ion exchange applications that require improved resolution and reproducibility.
