Catalog Number - 75020-SP150

Cogent HPS Phenyl™ Semi-Preparative HPLC Columns are designed for purification, fraction collection, and method scale-up of aromatic and structurally related compounds using reversed-phase chromatography. 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 provides unique aromatic selectivity through π-π interactions. HPS Phenyl™ is particularly effective for compounds that may be difficult to separate on conventional C18 phases and is widely used for purification and isolation of complex aromatic analytes.

75020-SP150 is packed with 5 µm HPS Phenyl™ particles in a 10 mm ID x 150 mm semi-preparative format. The 5 µm particle size provides excellent chromatographic efficiency while maintaining lower operating backpressure than smaller particles. The 10 mm internal diameter increases sample loading capacity compared to analytical columns, while the 150 mm length provides enhanced resolution and peak capacity for more demanding purification applications.

The HPS Phenyl™ stationary phase is especially useful for purification of 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 similar compounds when compared to traditional alkyl-bonded stationary phases. The 150 mm length offers enhanced separation performance while maintaining practical run times for routine purification workflows.
