HPLC Column, IEX WAX, 5um, 4.0mm ID x 50mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
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, enabling reliable anion exchange selectivity for acidic compounds and other negatively charged analytes. This stationary phase is widely used for ion exchange chromatography applications and serves as an excellent alternative for many USP L9 methods.
67590-05P-4 is a 50 mm x 4.0 mm ID analytical HPLC column packed with 5 µm WAX particles with a 100 Å pore size. The short 50 mm column length is ideal for rapid analyses, fast method development, and high-throughput laboratory workflows. The 4.0 mm ID format is commonly selected for legacy methods and applications requiring compatibility with conventional HPLC systems and typically operates at approximately 0.8–1.5 mL/min. The efficient 5 µm particle size provides excellent chromatographic performance for challenging ion exchange separations.
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, efficient particle technology, and rapid-analysis column dimensions makes it an excellent choice for demanding ion exchange chromatography methods. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
