HPLC Column, RP Phenyl, 5um, 4.0mm ID x 250mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
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.
68524-25P-4 is packed with 5 µm RP Phenyl™ particles featuring a 100 Å pore size in a 4.0 mm ID x 250 mm format. The 5 µm particle size provides excellent chromatographic efficiency while maintaining moderate operating backpressure. The extended 250 mm column length delivers maximum resolution and peak capacity, making it ideal for complex separations requiring enhanced analyte discrimination and retention.
The 4.0 mm ID x 250 mm format is well suited for aromatic and structurally related compounds in reversed-phase HPLC. Typical flow rates are approximately 0.8-1.2 mL/min depending on mobile phase composition and application requirements. This column format is frequently used for USP monograph methods and applications where maximum chromatographic resolution is required.
