HPLC Column, RP Phenyl, 5um, 4.6mm ID x 50mm 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 reduce 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 and new method development.
68524-05P is packed with 5 µm RP Phenyl™ particles featuring a 100 Å pore size in a 4.6 mm ID x 50 mm format. The 5 µm particle size provides excellent efficiency while maintaining lower operating backpressures than smaller particles. The short 50 mm column length is ideal for rapid analyses, method screening, and high-throughput laboratories where minimizing run times is important.
The 4.6 mm ID x 50 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.
