•  VertiPak™ HLP-SC SPE is mixed-mode, chemical modified
    Vinylpyrazine-Divinylbenzene Copolymer-Sulfonate,
    (VPZ-DVBS) polymeric sorbent offering both strong reverse
    phase interaction and strong cation-exchange interaction
    with interference-free extraction, compatability with LCMS
    or GC-MS.
•  Exhibits very high binding capacity over mixed-mode silica-
    C8/SCX 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
    bioloical fluid sample.
•  Typical applications include basic drugs and metabolites
    from biological 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.
