HPLC Column, IEX SCX, 5um, 4.0mm ID x 250mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent IEX SCX™ HPLC Columns are strong cation exchange chromatography columns designed for the separation, analysis, and purification of positively charged compounds. This stationary phase has been trusted by HPLC laboratories worldwide for many years and is manufactured using high-purity silica bonded with sulfonic acid functional groups. Because the sulfonic acid groups remain ionized across a broad pH range, the stationary phase maintains a strong negative charge, making it highly effective for the retention and separation of cationic analytes.
67586-25P-4 is packed with 5 µm IEX SCX™ particles in a 4.0 mm ID x 250 mm analytical HPLC column format. The 250 mm length provides increased retention and separation efficiency for complex ion exchange applications, while the 5 µm particle size delivers reliable performance, excellent loading characteristics, and moderate operating pressures. This format is particularly well suited for challenging separations requiring enhanced resolution and selectivity.
This column is an excellent choice for the analysis of basic compounds, charged pharmaceutical ingredients, amines, and other positively charged analytes. Its USP L9 equivalent chemistry makes it suitable for many ion exchange methods requiring strong cation exchange selectivity. The high-purity silica support and robust bonded phase provide reproducible performance for pharmaceutical, chemical, environmental, and research applications.
