HPLC Column, HPS C8 Octyl, 5um, 4.6mm ID x 50mm Length, 120A. Cogent Brand. 1 EA.
Additional Information:
Cogent HPS C8™ HPLC Columns are designed for reversed-phase separations requiring moderate hydrophobic retention, excellent peak shape, and reproducible performance. Built on a unique 120Å silica support with monofunctional octyl (C8) bonding and full double end capping, this stationary phase is widely used as an alternative for USP L7 methods and for new method development. The HPS product line was developed to provide a high-value option for laboratories seeking performance characteristics commonly associated with well-established octyl phases used throughout the pharmaceutical, environmental, and analytical testing industries.
75008-05P is packed with 5 µm HPS C8™ particles in a 4.6 mm ID x 50 mm analytical format. The 5 µm particle size provides reliable efficiency with lower operating backpressure than smaller particles, making this column suitable for routine analytical HPLC systems. The short 50 mm length is ideal for rapid method development, high-throughput analysis, and fast screening applications where shorter run times are desired.
The HPS C8™ stationary phase is well suited for hydrophobic and neutral compounds analyzed under reversed-phase conditions. Compared to C18 columns, the octyl phase generally provides shorter retention, making it useful for compounds that are excessively retained on more hydrophobic stationary phases. This column is particularly effective for long-chain fatty acids and is frequently selected as a scouting column during analytical and preparative method development.
