HPLC Column, HPS Phenyl, 5um, 2.1mm 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 for challenging separations involving aromatic compounds, positional isomers, and structurally related analytes. The HPS product line was developed to provide a high-value option for laboratories seeking performance characteristics comparable to established premium phenyl columns used throughout pharmaceutical, environmental, and analytical laboratories.
75020-15P-2 is packed with 5 µm HPS Phenyl™ particles in a 2.1 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 difficult separations. The narrow-bore format reduces solvent consumption and is especially well suited for LC-MS applications requiring high sensitivity and efficient mobile phase utilization.
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 frequently provides improved separation of structurally related compounds that may not be adequately resolved on traditional C18 columns. This column is a popular choice for LC-MS methods where selectivity, sensitivity, and reproducible performance are essential.
