C18/OH – Octadecyl

Description of Base Sorbent for Solid Phase Extraction

  • 40μm irregularly-shaped silica
  • 60 Angstrom mean porosity

The primary retention mechanism is moderately non-polar with a typical sample matrix of aqueous biological fluids.

The lack of endcapping results in significant polar secondary interactions.
