•  VertiPak™ HLP-WC SPE is mixed-mode, highly cross-linked
    Vinylpyrazine-Divinylbenzene Copolymer-Carboxzypropyl,
    (VPZ-DVBC) polymeric sorbent offering both strong
    reversed phase interaction and weak cation-exchange
    interaction with interference-free extraction, compatability
    with LC-MS or GC-MS.
•  Needs no condition solvent, aqueous sample can be loaded
    directly to the dry sorbent bed.
•  Exhibits very high binding capacity over mixed-mode   
    silicabased sorbent, up to 30% of sorbent weight allowing
    larger sample loads or a smaller sorbent bed resulting in
    high, reproducible recoveries and less solvent usage.
•  Exhibits excellent mass transfer and mechanical strength
    for basic polar compounds in an aqueous sample or a
    biological fluid sample without base modifiers.
•  Typical applications include basic drugs and metabolites
    from biologial fluids, environmetal pollutants from water,
    drugs of abuse and metabolites from urine e.g. amphetamine,
    methamphetamine, opiate, barbiturate, cocaine, THC.
•  Tube format is available in 4 tube sizes.
•  Tubes are packaged in zip sealing bag protective from
    moisture and light.
•  Includes a Performance report including the QC results, lot
    chromatogram and lot recovery test.
