HPLC Column, IEX SCX, 5um, 4.0mm ID x 150mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent IEX SCX is a strong cation exchange (SCX) HPLC stationary phase manufactured using high-purity silica and sulfonic acid functional groups that maintain a permanent negative charge across a wide pH range. This strong cation exchange mechanism provides reliable retention and separation of positively charged analytes, making the column suitable for ion exchange chromatography methods involving basic compounds, amines, peptides, pharmaceuticals, and other cationic species. The stationary phase is an excellent alternative for USP L9 methods and applications requiring robust cation exchange selectivity.
67586-15P-4 is a 150 mm x 4.0 mm ID analytical column packed with 5 µm SCX particles with a 100 Å pore size. The 150 mm length provides increased resolving power for more demanding ion exchange separations while maintaining excellent chromatographic efficiency. The 5 µm particle size delivers higher plate counts, sharper peaks, and improved chromatographic performance compared to larger particle packings. The 4.0 mm ID format is commonly selected for legacy methods and typically operates at approximately 0.8–1.5 mL/min, making it well suited for conventional HPLC systems.
This USP L9 column is particularly useful for the separation and purification of positively charged compounds, including basic pharmaceuticals, amines, peptides, alkaloids, and other ionic species. The combination of strong cation exchange functionality, high efficiency, and increased column length makes it ideal for method development, quality control testing, impurity profiling, and complex ion exchange separations requiring greater chromatographic resolution. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
