CN Solid Phase Extraction Column Plates

B&M® CN is a cyanopropyl silica gel-based extraction column that can be used as a non-polar adsorbent to extract polar and non-polar molecules from aqueous solutions, as well as polar molecules from relatively non-polar solvents. In addition, cyanopropyl acts as a complex ligand to enrich some metal ions in aqueous solution.
Cyanopropyl is a weakly hydrophobic filler of the silica matrix and can be used as a direct or reverse phase adsorbent. Under the conditions of the reversed phase, nonpolar or slightly polar acidic, neutral and basic compounds are extracted from aqueous solutions. Under direct phase conditions, polar compounds are extracted from nonpolar organic solutions. In addition, cyanopropyl acts as a complex ligand to enrich some metal ions in aqueous solution. For strong hydrophobic substances that bind irreversibly at the stationary C18 phases, the stationary CN phases are a more suitable choice.   Equivalent to Waters Sep-Pak CN.
