HPLC Column, RP Cyano, Wide Pore, 3um, 2.1mm ID x 150mm Length, 300A. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Cyano™ Wide Pore is a versatile reversed-phase HPLC stationary phase designed for the separation of larger polar and neutral compounds. Manufactured using a three-carbon ligand with a terminal cyano (CN) functional group bonded to ultra-high purity silica, this 300 Å wide pore stationary phase provides selectivity distinct from traditional C18, C8, and phenyl phases while offering increased accessibility for large analytes. As a USP L10 equivalent phase, it is particularly useful for proteins, peptides, enzymes, natural products, and other larger molecules that benefit from wide pore chromatography.
68334-15P-2-3M is an HPLC column packed with 3 µm RP Cyano™ Wide Pore particles featuring a 300 Å pore size in a 2.1 mm ID x 150 mm format. This narrow-bore configuration combines maximum chromatographic resolution with reduced solvent consumption and excellent compatibility with LC-MS instrumentation. The 150 mm length provides significantly greater peak capacity and resolving power than shorter column formats, while the wide pore structure improves analyte access to the bonded phase for larger compounds. Typical operating flow rates are approximately 0.2–0.3 mL/min. Standard HPLC systems used with 2.1 mm ID columns must be capable of precise and reproducible low-flow operation.
This column is particularly useful for large polar or neutral compounds including proteins, peptides, enzymes, and natural products analyzed by reversed-phase HPLC and LC-MS methods. Compared to non-modified silica columns, the RP Cyano™ Wide Pore phase typically provides shorter retention times and faster equilibration between runs. The combination of wide-pore accessibility, USP L10 selectivity, and high-resolution performance makes this column an excellent choice for demanding bioanalytical, pharmaceutical, and research applications.
