Catalog Number - 68334-05P-4

Cogent RP Cyano™ is a versatile reversed-phase HPLC stationary phase designed for the separation of polar and neutral compounds. Manufactured using a three-carbon ligand with a terminal cyano (CN) functional group bonded to ultra-high purity silica, this stationary phase provides selectivity distinct from traditional C18, C8, and phenyl phases. As a USP L10 equivalent phase, it is widely used for method replacement, method development, and applications requiring reduced hydrophobic retention, faster equilibration, and alternative selectivity.

68334-05P-4 is an HPLC column packed with 3 µm RP Cyano™ particles featuring a 100 Å pore size in a 4.0 mm ID x 50 mm format. The short 50 mm length is optimized for rapid analyses and high sample throughput, while the 3 µm particles provide greater efficiency and sharper peaks than comparable 5 µm columns. Typical operating flow rates are approximately 0.8–1.5 mL/min depending on mobile phase composition, temperature, and system configuration.

Often selected for polar and neutral compounds in reversed-phase HPLC, this Cyano phase typically provides shorter retention times and faster equilibration than non-modified silica columns. The short column format is particularly useful for rapid screening, routine analysis, and method development applications where speed and productivity are important.
