•  VertiPak™ HLP SPE is hydrophilic, highly cross-linked
    Vinylpyrazine-Divinylbenzene copolymer (VPZ-DVB)
    polymeric sorbent offering primary strong reversed phase
    interaction and secondary strong anion-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 silica-C18 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 polar and non-polar compounds in an aqueous sample
    or a biological fluid sample.
•  Typical applications include aromatics compounds, phenols
    from water, nitroaromatics from water, pesticides from
    environmental samples, drugs and metabolites from
    biological fluids.
•  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.
