Equisorb C8 is a reversed-phase HPLC column packed with fully porous, high-purity silica particles bonded with octyl groups. This medium-chain alkyl phase provides moderate hydrophobic retention, offering shorter analysis times compared to C18 columns while maintaining good selectivity and resolution. Equisorb C8 is well suited for compounds that elute too strongly on C18 and is ideal for routine quality control, method development, and the analysis of moderately non-polar analytes.
Equisorb C8 offers reliable and efficient chromatographic performance – ideal for reversed-phase HPLC workflows requiring reduced retention and robust peak shape.
