    Polar SPE

    All the phases on this page extract analytes from non-polar (typically solvent) matrices using polar retention mechanisms.

    The strength and selectivity of retention varies with sorbent type and matrix (solvent) characteristics.

    cond-equil-load-wash-elute

    Polar phase with enhanced capacity for acidic analytes.

    ISOLUTE® AL-A

    Polar, neutral phase, extracts electron rich aromatic compounds or those containing N, O, P & S heteroatoms.

    ISOLUTE® AL-N

    Polar phase with enhanced capacity for basic analytes.

    ISOLUTE® AL-B

    Retains analytes via dipole-dipole interactions.  Good for analytes that are difficult to elute from other polar sorbents.

    ISOLUTE® CN

    Retains analytes via hydrogen bonding and dipole-dipole interactions. Weaker retention than SI.

    ISOLUTE® DIOL

    An alternative to SI medias. Minimal retention of basic compounds. Activated for separation of chlorinated pesticides.

    ISOLUTE® FL

    Highest capacity for polar interactions. retains analytes via hydrogen bonding, dipole-dipole and weak cation exchange interactions (if trace water is present).

    ISOLUTE® SI

    Retains analytes via hydrogen bonding and dipole-dipole interactions.

    ISOLUTE® NH2

    Retains analytes via hydrogen bonding and dipole-dipole interactions.

    ISOLUTE® PSA
