Chromabond HLB, 60mg, 1.5mL, 60µm, 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
