    Non-Polar SPE

    All the SPE phases on this page extract analytes from aqueous samples using a non-polar (hydrophobic) retention mechanism. The most retentive phases are listed first. 
    • Extract polar analytes (with low hydrophobic character) using the most retentive phases
    • Consider less retentive phases for extraction of non-polar (more hydrophobic) analytes
    cond-equil-load-wash-elute

    Highly retentive phase, extracts very polar analytes which are not retained by silica based C18 media.

    ISOLUTE® ENV+

    Retains a broad range of polar and non-polar analytes. No secondary interactions. Used for PFAS in method EPA537.

    ISOLUTE® 101

    Retains a broad range of polar and non-polar analytes. Secondary silanol interactions may enhance recovery of basic analytes.

    ISOLUTE® C18

    Retains a broad range of polar and non-polar analytes. Efficiently end-capped to minimize secondary silanol interactions.

    ISOLUTE® C18(EC)

    Retentive phase with high secondary silanol interactions for enhanced retention of basic compounds.  Use in pH range 2-8.  

    ISOLUTE® MFC18

    Medium retentive phase for polar and non-polar analytes.  Secondary silanol interactions may enhance recovery of basic compounds.

    ISOLUTE® C8

    Medium retentive phase for non-polar analytes. Efficiently end-capped to minimize secondary silanol interactions.

    ISOLUTE® C8(EC)

    Medium retentive phase for extraction of polar and non-polar analytes.  Secondary silanol interactions may enhance recovery of basic compounds.  Different selectivity compared to C8 media.

    ISOLUTE® PH

    Less retentive phase for extraction of  non-polar analytes.  Secondary silanol interactions may enhance recovery of basic compounds. 

    ISOLUTE® C4
