HPLC Column, HPS Phenyl, 5um, 4.6mm ID x 150mm Length, 120A. Cogent Brand. 1 EA.
Additional Information:
Cogent HPS Phenyl™ HPLC Columns are designed for reversed-phase separations where aromatic selectivity and π-π interactions provide advantages over conventional alkyl-bonded phases. Manufactured using a monofunctional four-carbon ligand with an attached phenyl group bonded to high-purity 120Å silica and fully end capped for excellent peak shape and reproducibility, this stationary phase is widely used as an alternative for USP L11 methods and for developing methods involving structurally similar aromatic compounds. The HPS product line was developed to provide a high-value option for laboratories seeking performance characteristics comparable to established premium phenyl phases.
75020-15P is packed with 5 µm HPS Phenyl™ particles in a 4.6 mm ID x 150 mm analytical format. The 5 µm particle size provides reliable chromatographic efficiency with lower operating backpressure than smaller particles, while the 150 mm column length delivers enhanced resolution and peak capacity for more demanding separations. This format is frequently selected when additional resolving power is needed while maintaining compatibility with standard analytical HPLC systems.
The HPS Phenyl™ stationary phase is especially useful for separating positional isomers, tocopherols, flavonoids, polynuclear aromatic hydrocarbons, nitro-aromatic compounds, active pharmaceutical ingredients (APIs), natural products, and related compounds. The unique aromatic selectivity often provides improved separation of structurally related compounds that may be difficult to resolve on traditional C18 columns, making it an excellent choice for challenging reversed-phase applications.
