Extracting non-polar compounds


 C18 sorbent is composed of endcapped octadecyl-bounded silica gel particles and retains non-polar compounds by hydrophobic interactions. It can retain most organic compounds and is widely used in areas such as environmental monitoring and food safety.



  • High carbon content
  • Fully endcapped surface coverage, reducing interference from basic and polar compounds
  • Stable over a broader pH range



Carbon content: 17.6%
Surface area: 300 m 2/g
Particle size: 40-60 μm
Pore size: 120 Å



  • Analysis of drugs, poisons, pollutants and their metabolites in biological matrices
  • Separation of biomolecules such lipids, antibiotics, bile acids and saccharides
  • Determination of mycotoxins such as fumonisins in foods
  • Determination of preservatives in cosmetics and skin care products
