HPLC Column, IEX WCX, 5um, 4.0mm ID x 150mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent IEX WCX™ HPLC Columns are weak 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 carboxylic acid functional groups. Unlike strong cation exchangers, the weak cation exchange functionality provides pH-dependent ionization, offering unique selectivity and increased flexibility for challenging ion exchange separations.
67591-15P-4 is packed with 5 µm IEX WCX™ particles in a 4.0 mm ID x 150 mm analytical HPLC column format. The 150 mm column length provides an excellent balance of retention, efficiency, and analysis time, while the 5 µm particle size delivers reliable chromatographic performance with moderate operating pressures. The carboxylic acid functional groups provide effective cation exchange interactions throughout their useful pH range, making this column particularly useful for compounds whose retention can benefit from controlled ionization mechanisms.
This column is an excellent choice for the analysis and purification of basic compounds, positively charged analytes, amines, peptides, and other ionic species. Its USP L9 equivalent chemistry makes it suitable for ion exchange methods requiring cation exchange selectivity, while the weak cation exchange mechanism can provide alternative selectivity compared to strong cation exchange columns. The high-purity silica support and carefully controlled bonded phase chemistry provide reproducible performance for pharmaceutical, biotechnology, chemical, and research applications.
