    Ion Exchange SPE

    All the SPE phases on this page extract ionizable analytes from aqueous samples using an ion exchange retention mechanism.
    • Extract basic analytes using cation exchange SPE
    • Extract acidic analytes using anion exchange SPE
    cond-equil-load-wash-elute

    A strong cation exchange sorbent used to extract weakly basic analytes.

    ISOLUTE® SCX

    A strong cation exchange sorbent used to extract weakly basic analytes. Weak secondary non-polar interactions, so analytes can be eluted under aqueous conditions. Equivalent to PRS media.

    ISOLUTE® SCX-2

    A strong cation exchange sorbent used to extract weakly basic analytes. Enhanced secondary non-polar interactions.

    ISOLUTE® SCX-3

    A weak cation exchange sorbent used to extract strongly basic (e.g quaternary amine) analytes.

    ISOLUTE® CBA

    A strong anion exchange sorbent used to extract weakly acidic analytes.  Supplied with a chloride counter ion.

    ISOLUTE® SAX

    A strong anion exchange sorbent used to extract weakly acidic analytes. Supplied with an acetate counter ion for enhanced extraction of very polar acids.

    ISOLUTE® PE-AX

    A weak anion exchange sorbent used to extract strongly acidic analytes.

    ISOLUTE® NH2

    A weak anion exchange sorbent used to extract strongly acidic analytes.  Will also complex with certain metal ions.

    ISOLUTE® PSA
