C18N SPE Cartridge

Extracting polar and non-polar compounds, enriching metal ions


Finetech® C18N sorbent is composed of octadecyl-bounded silica gel particles. In addition to strong retention for non-polar compounds by hydrophobic interactions, it provide additional retention for basic compounds due to residual silanols. C18N is a general-purpose sorbent capable of retaining both polar and non-polar compounds.
