HPLC Column, HPS C8 Octyl, 5um, 4.6mm ID x 150mm 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. Manufactured using 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 similar to widely adopted octyl phases used throughout pharmaceutical, environmental, food, and analytical laboratories.
75008-15P is packed with 5 µm HPS C8™ particles in a 4.6 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 offers enhanced resolution and peak capacity for more challenging separations. This format is frequently selected when greater separation power is required without moving to a longer 250 mm column.
The HPS C8™ stationary phase is well suited for hydrophobic and neutral compounds analyzed using reversed-phase chromatography. Compared to C18 columns, the octyl phase generally provides shorter retention, making it useful for compounds that are overly retained on more hydrophobic stationary phases. This column is particularly effective for long-chain fatty acids and is one of the most popular choices for routine analytical HPLC methods requiring an excellent balance of retention, selectivity, and resolution.
