Description of  SPE C18 cartridge

Hawach C18 solid phase extraction (SPE) cartridge uses octadecyl silica as a filler to retain non-polar compounds by strong hydrophobic interaction. A C18 cartridge solid phase extraction is a specific type of sorbent cartridge used for the extraction and purification of analytes from liquid samples. The filler retains most of the organic matter and is widely used in the fields of environmental and food safety. The stationary phase of the SPE cartridge consists of hydrophobic C18 (Octadecyl) functional groups chemically bonded to the silica support. SPE C18 is a popular reversed-phase material used in chromatography due to its excellent retention and separation properties for a wide range of compounds.

Features of Reversed Phase C18 SPE Cartridge

  • Withstand higher pH environments;
  • High carbon loading, strong hydrophobicity;
  • Full coverage of caps to reduce alkaline and polar compound interference.
  • C18 immobilization provides good selectivity for non-polar and moderately polar compounds.

Parameters of SPE C18 cartridge

  • Carbon content: 17.6%;
  • Particle size: 40-60μm;
  • Average pore size: 120Å;
  • Specific surface area: 300 m²/g.

Applications of C18 solid phase extraction

  • Analysis of pigments and sugars in food;
  • Desalting the aqueous solution prior to ion exchange;
  • Detection of pesticides and veterinary drug residues in food, such as antibiotics;
  • Detect organic pollutants in the soil, such as polycyclic aromatic hydrocarbons (PAHs);
  • Particularly effective for the extraction and purification of hydrophobic compounds, such as lipids, drugs, and organic pollutants.
