•  VertiPak™ HBP SPE is hydrophobic, highly cross-linked
    polystyrene divinylbenzene copolymer (PS-DVB) polymeric
    sorbent offering 100% reversed phase interaction and
    interference-free extraction, compatability with LC-MS or
    GC-MS.
•  Exhibits very high binding capacity over silica, up to
    30% of sorbent weight allowing larger sample loads or a
    smaller sorbent bed resulting in better analyte
    concentration.
•  Needs no addition of amine modifiers, buffers and acids
    due to no silanol in PS-DVB.
•  Typical applications include aromatics compounds, phenols
    from water, nitroaromatics from water, pesticides from
    environmental samples, PAHs from oil.
•  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.
