    Mixed-Mode SPE

    All the SPE phases on this page extract ionizable analytes from biological fluids using a robust dual retention mechanism, which allows additional wash steps for enhanced extract purity.
    • Extract basic analytes using mixed-mode non-polar/cation exchange sorbents
    • Extract acidic analytes using mixed-mode non-polar/anion exchange sorbents

    Extract basic analytes using combined non-polar and strong cation exchange retention mechanisms.

    Extract basic analytes using combined non-polar and strong cation exchange retention mechanisms. Strong non-polar character for enhanced recovery of more polar compounds.

    Extract basic analytes using combined non-polar and strong cation exchange retention mechanisms. Reduced non-polar character for higher purity extracts of more hydrophobic compounds.

    Extract strongly basic (e.g. quaternary amine)  analytes using combined non-polar and weak cation exchange retention mechanisms.

    Extract acidic analytes using combined non-polar and strong anion exchange retention mechanisms.
