Strong Cation Mixed-Mode Solid Phase Extraction (SPE)
A strong cation-exchange functionalized polymeric sorbent that allows for complete retention of basic compounds with a pKa less than 10.5, making 100% organic wash conditions possible. A 100% organic wash ensures that the maximum amount of interferences are removed from the target compound.
