Catalog Number - 75025-SP50

Cogent HPS Cyano™ Semi-Preparative HPLC Columns are designed for purification, fraction collection, and method scale-up of polar and moderately retained compounds using reversed-phase chromatography. Manufactured using a monofunctional three-carbon ligand with a terminal cyano functional group bonded to high-purity 120Å silica and fully end capped, this stationary phase provides excellent reproducibility, moderate hydrophobicity, and rapid equilibration characteristics. HPS Cyano™ is particularly useful when a purification requires less retention than C18 phases while maintaining excellent selectivity and recovery.

75025-SP50 is packed with 5 µm HPS Cyano™ particles in a 10 mm ID x 50 mm semi-preparative format. The 5 µm particle size provides excellent chromatographic efficiency with lower operating backpressure than smaller particles. The 10 mm internal diameter increases sample loading capacity compared to analytical columns, while the short 50 mm length is optimized for rapid purification, high-throughput fraction collection, and semi-preparative method development.

The HPS Cyano™ stationary phase is particularly useful for purification of polar and neutral compounds where shorter retention times and faster equilibration are desired. Compared to non-modified silica columns, the cyano phase provides more reproducible reversed-phase behavior while maintaining efficient purification performance. The short column length makes this format ideal for rapid purification workflows, scouting studies, and analytical-to-semi-preparative method transfer.
