ODS C18-N products have silica based reverse phase sorbents bonded with octadecylsilane without endcapping. The extra silanol residue of the sorbent provides additional polar interactions associated with surface silanol groups which enhance the retention of basic compounds. These columns are similar to Agilent AccuBond C18 and BondElute C18 OH.
