HPLC Column, IEX SAX, 10um, 4.6mm ID x 100mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent IEX SAX is a strong anion exchange (SAX) HPLC stationary phase manufactured using high-purity silica and quaternary amine functional groups that maintain a permanent positive charge across a wide pH range. This strong anion exchange mechanism provides reliable retention and separation of negatively charged analytes, making the column suitable for ion exchange chromatography methods involving inorganic anions, organic acids, biomolecules, and other ionic compounds. The stationary phase is an excellent alternative for USP L9 methods and applications requiring robust anion exchange selectivity.
67085-10P is a 100 mm x 4.6 mm ID analytical column packed with 10 µm SAX particles with a 100 Å pore size. The 100 mm length provides an excellent balance between chromatographic resolution and analysis time, while the larger 10 µm particle size delivers low backpressure and supports higher flow rates compared to smaller particle packings. Typical operating flow rates are approximately 1.0–3.0 mL/min, making this column well suited for conventional HPLC systems and routine ion exchange methods.
This USP L9 column is particularly useful for the separation and purification of negatively charged compounds, including organic acids, inorganic anions, nucleotides, and other ionic species. The combination of strong anion exchange functionality, high capacity, and low backpressure makes it ideal for routine analytical testing, method development, quality control laboratories, and purification workflows.
