HPLC Column, HPS Phenyl, 5um, 4.6mm ID x 100mm 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 traditional 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 well-established premium phenyl phases.
75020-10P is packed with 5 µm HPS Phenyl™ particles in a 4.6 mm ID x 100 mm analytical format. The 5 µm particle size provides reliable chromatographic efficiency with lower operating backpressure than smaller particles, while the 100 mm column length delivers an excellent balance between analysis speed and chromatographic resolution. This format is frequently selected for routine analytical methods, pharmaceutical testing, and method development applications.
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 compounds that may coelute on conventional C18 columns, making it an excellent choice for challenging analytical separations.
