HPLC Column, RP Phenyl, 5um, 4.6mm ID x 150mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Phenyl™ HPLC Columns are designed for reversed-phase separations where aromatic selectivity is beneficial. Manufactured using ultra-high purity silica bonded with a three-carbon linker and terminal phenyl functionality, this stationary phase is fully double end-capped to minimize secondary interactions and provide highly reproducible chromatographic performance. RP Phenyl™ is an excellent alternative for USP L11 methods and is commonly selected for both established methods and new method development.
68524-15P is packed with 5 µm RP Phenyl™ particles featuring a 100 Å pore size in a 4.6 mm ID x 150 mm format. The 5 µm particle size provides excellent chromatographic efficiency while maintaining moderate operating backpressure. The 150 mm column length delivers increased resolution and peak capacity compared to shorter columns, making it ideal for complex separations and USP monograph methods that require greater chromatographic performance.
The 4.6 mm ID x 150 mm format is well suited for aromatic and structurally related compounds in reversed-phase HPLC. Typical flow rates are approximately 0.8-1.5 mL/min depending on mobile phase composition and application requirements. This column size is one of the most widely used formats for routine pharmaceutical analysis and USP monograph methods.
