Cleanert S C18-N is a type of C18 sorbent bonded to silica without end-capping modification, providing extra silanol residuals around the root of alkyl chain on silica surface. The extra silanol silica of the sorbent provides additional polar interactions associated with surface silanol groups which enhance the retention of basic compounds.
