Bond Elut Plexa PCX nonpolar/cation-exchange SPE is suitable for polar and nonpolar basic analytes.

• Faster flow rates improve productivity
• Extraction cleanliness and reduced ion suppression improves precision
• Simplified, single method for ease-of-use

Bond Elut Plexa PCX uses a polymeric cation-exchange resin that combines the outstanding properties of Bond Elut Plexa with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes, and improves sensitivity in the determination of basic compounds. Plexa PCX can also be used for selective fractionation of basic, acidic, and neutral analytes.
