CN SPE Cartridge

Extracting polar and non-polar compounds, enriching metal ions

Finetech® CN is a cyanopropyl bonded silica sorbent, weakly hydrophobic, used as normal phase or reversed phase. It is able to extract apolar or weakly polar acids, neutrals and bases from aqueous solutions when used as a reversed phase sorbent. It is also able to extract polar compounds from nonpolar organic solutions when used as a normal phase sorbent. Besides, cyanopropyl is a ligand that can be used to enrich some metal ions.

​

CN sorbent will be a better choice to extract strongly hydrophobic compounds which may bind to C18 sorbent irreversibly.
