HPLC Column, RP C8 Octyl, 10um, 4.0mm ID x 100mm 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.
68008-10P-4 is an analytical HPLC column with dimensions of 4.0 mm ID x 100 mm length, packed with 10 µm RP C8 Octyl particles featuring a 100 Å pore size. The 100 mm length provides a balance between analysis speed and chromatographic resolution, making it suitable for routine analytical methods, method development, and quality control applications. 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 C8 stationary phase delivers less retention than C18 columns, which can reduce run times while maintaining effective separation. Its balanced selectivity and robust performance make it a practical choice for routine laboratory testing, pharmaceutical analysis, and USP L7 methods. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
