The ISOLUTE HCX series of mixed-mode SPE sorbents is based on a combination of strong cation exchange and non-polar chemistries. Basic drugs are retained by two primary retention mechanisms. This allows a rigorous interference elution regime to be used to elute interferences retained by either non-polar or cation exchange interactions alone. Only analytes with both non-polar and basic characteristics are extracted using the ISOLUTE HCX series of sorbents, providing an extremely pure final extract.
