HPLC Column, RP C8 Octyl, 10um, 4.0mm ID x 50mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C8 Octyl is a reversed-phase HPLC stationary phase manufactured using high-purity silica with traditional octyl (C8) silane bonding and complete double endcapping. The moderate hydrophobicity of the C8 ligand provides an excellent balance between retention and elution strength, making it suitable for a broad range of hydrophobic and neutral compounds. This stationary phase is commonly selected as an alternative for USP methods that specify L7 column classifications and is frequently used when reduced retention compared to C18 phases is preferred.
68008-05P-4 is an analytical HPLC column with dimensions of 4.0 mm ID x 50 mm length, packed with 10 µm RP C8 Octyl particles featuring a 100 Å pore size. The short 50 mm length is ideal for rapid method development, screening studies, and high-throughput analyses where fast run times are prioritized. The 10 µm particle size provides lower operating backpressure while supporting higher flow rates than smaller particle columns.
This column is well suited for analysis of hydrophobic and neutral compounds, including long-chain fatty acids and related analytes. The shorter column format also makes it an effective scouting column for preparative method development, allowing rapid evaluation of retention and selectivity prior to scale-up. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
