UHPLC Column, RP Cyano, 1.8um, 100A. 2.1mm ID x 50mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Cyano™ is a versatile reversed-phase UHPLC stationary phase designed for polar and neutral compound separations where reduced retention and rapid equilibration are desired. Manufactured with a cyanopropyl bonded phase on ultra-high purity silica and supplied without endcapping, this chemistry provides distinct selectivity compared to traditional alkyl phases. RP Cyano™ is commonly used as an alternative for USP L10 methods and offers shorter retention times than many conventional reversed-phase columns while maintaining excellent chromatographic performance.
68134-05P-2 is a UHPLC column packed with 1.8 µm RP Cyano™ particles featuring a 100 Å pore size in a 2.1 mm ID x 50 mm format. The short 50 mm length is optimized for rapid analyses and high sample throughput, while the sub-2 µm particle technology provides exceptional efficiency and increased peak capacity. This column is specifically engineered for high-pressure UHPLC applications and is designed to take full advantage of UHPLC instrumentation capable of operating at the elevated pressures generated by 1.8 µm particles. Typical operating flow rates are approximately 0.2–0.4 mL/min. Because of the low flow rates required by 2.1 mm ID columns, standard HPLC systems must be capable of precise and reproducible low-flow operation if used with this column.
This column is particularly useful for polar and neutral compounds requiring reversed-phase retention with fast equilibration and efficient separations. The 2.1 mm ID format is commonly used for LC-MS applications due to reduced solvent consumption and excellent compatibility with mass spectrometric detection.
