Chromabond HLB, 10mg, 1.5mL, 30µm, 65Å, 96 Well Plate

Description: The enrichment of hydrophilic analytes from polar matrices is a challenge because they often cannot be retained by C18 / C8-modified silica or hydrophobic polymer adsorbents. To overcome this issue MACHEREY-NAGEL developed CHROMABOND® HLB, a hydrophilic-lipophilic balanced N-vinylpyrrolidone-divinylbenzene copolymer. Its lipophilic backbone interacts with nonpolar hydrocarbon residues of the analytes while the linked hydrophilic groups interact with polar functional groups to provide enhanced retention.

Key features:

  • Applicable for a wide range of analyte polarities
  • Enhanced retention for polar compounds
  • High loadability and outstanding performance
  • Water wettable – even if bed runs dry, SPE can be continued
  • The alternative to Oasis® HLB

    Technical characteristics:
     Hydrophilic-lipophilic balanced N-vinylpyrrolidone-divinylbenzene copolymer, pH stability 1–14 · Particle size 60 μm and 30 μm, pore size 65 Å, specific surface 750 m2/g,

    Typical Applications:

  • Polar organic molecules from polar matrices e.g. Sulfonamides. Pesticides, Chloramphenicol, Iodinated contrast media
