The Cogent Silica-C™ columns are totally inorganic and are made, completely of silicon, hydrogen and oxygen. These columns are designed mostly for improved Normal Phase HPLC methods.

Any apparent retention of non polar compounds you may observe is most likely due to Aqueous Normal Phase ANP retention mechanism and your method.
