HPLC Column, IEX WAX, 5um, 4.6mm ID x 50mm 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 exhibits a positively charged surface within its useful pH range, providing reliable anion exchange selectivity for acidic compounds and other negatively charged analytes. This chemistry is widely used for ion exchange chromatography applications and serves as an excellent alternative for many USP L9 methods.
67590-05P is a 50 mm x 4.6 mm ID analytical HPLC column packed with 5 µm WAX particles featuring a 100 Å pore size. The shorter 50 mm length is ideal for fast analyses, high-throughput laboratories, rapid screening methods, and method development workflows where speed is important. 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 an effective balance of sensitivity, robustness, and sample loading capacity.
This weak anion exchange column is particularly well suited for the analysis and purification of acidic compounds, organic acids, biomolecules, pharmaceuticals, and other negatively charged species. The combination of high-purity silica, selective WAX functionality, and efficient 5 µm particles provides reproducible chromatography and dependable performance for challenging ion exchange separations.
