UHPLC Column, RP Phenyl, 1.8um, 100A. 2.1mm ID x 50mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Phenyl™ is a reversed-phase UHPLC stationary phase designed to provide enhanced selectivity for aromatic and structurally related compounds. Manufactured using a propyl linker with a terminal phenyl ring bonded to ultra-high purity silica and fully double end capped, this phase offers unique π-π interaction mechanisms that can improve the separation of compounds that may be difficult to resolve on traditional alkyl phases. It is particularly useful for aromatic pharmaceuticals, positional isomers, flavonoids, tocopherols, polynuclear aromatic hydrocarbons, nitro-aromatic compounds, and many natural products.
68124-05P-2 is a UHPLC column packed with 1.8 µm RP Phenyl™ particles featuring a 100 Å pore size in a 2.1 mm ID x 50 mm format. This is one of the most popular RP Phenyl™ column configurations due to its combination of high efficiency, low solvent consumption, and excellent LC-MS compatibility. The short 50 mm length is optimized for rapid analyses and high sample throughput, while the sub-2 µm particle technology delivers outstanding chromatographic efficiency and peak capacity. Typical operating flow rates are approximately 0.2–0.4 mL/min, requiring reliable low-flow performance from the instrument.
Designed specifically for high-pressure UHPLC applications, this column is ideal for aromatic compounds, positional isomers, APIs, flavonoids, natural products, and other phenyl-containing analytes. The 2.1 mm ID format is frequently selected for LC-MS workflows where sensitivity, throughput, and solvent savings are important.

Important Notes
Specifically designed for UHPLC operation and high-pressure reversed-phase chromatography
Delivers maximum performance when used on a UHPLC system designed for sub-2 µm particle columns
May be used on compatible HPLC systems only if instrument pressure limits are not exceeded and low-flow operation is reliable
Sub-2 µm particles generate significantly higher backpressure than conventional HPLC columns
The 2.1 mm ID format is commonly used for LC-MS applications and reduced solvent consumption
Standard HPLC systems must be capable of precise and reproducible operation at approximately 0.2–0.4 mL/min
Enhanced selectivity for aromatic and phenyl-containing compounds compared to traditional alkyl phases
Samples should be filtered through a 0.2 µm syringe filter prior to injection
