    EVOLUTE® EXPRESS WCX

    Advanced Polymeric SPE for Strong Bases

    EVOLUTE® EXPRESS WCX combines non-polar and weak cation exchange functionality for extraction of strongly basic analytes (e.g. quaternary amines) from biological fluids and other aqueous samples through a dual, mixed-mode mechanism.

    This provides additional selectivity and clean-up for complex samples, with salts, phospholipids and proteins eliminated from extracts.

    Available in a variety of formats, including  96-well plates and SPE columns, and two different particle sizes (30 µm and 50 µm) depending on application requirements. 

    The sorbent consists of the EVOLUTE® backbone, surface modified with carboxylic acid groups. Sorbent performance is not compromised by drying during processing.

    Highlights 
    • High, reproducible recoveries for strongly basic analytes
    • Ideal for analytes that are unstable under basic conditions (e.g. catecholamines)
    • Eliminate salts, phospholipids and proteins from biofluid extracts, and minimise ion suppression
    • Fast simple generic methodology
    • Available in EVOLUTE® EXPRESS SPE columns and plates for fast  Load-Wash-Elute procedures
