Copure® C18A SPE Cartridges

Copure® C18A SPE Cartridges

Extracting non-polar compounds

Copure ® C18A sorbent is composed of octadecyl-bounded silica gel particles and retains non-polar compounds by hydrophobic interactions.

Hydrophilic surface modification makes C18A wettable and prevents its carbon chains from collapsing in aqueous solution. Due to its compatibility with aqueous mobile phases, even pure water can be used, and silica particles are more stable.


  • Compatible with aqueous solutions
  • Additional retention for polar compounds


Carbon content: 12%
Surface area: 300 m 2/g
Particle size: 40-75 μm
Pore size: 100 Å


  • Desalting of biological macromolecules such as nucleic acids, proteins and peptides.
  • Determination of drugs, pesticides and organic pollutants in water, such as polycyclic aromatic hydrocarbons (PAHs)
