Extracting acidic compounds

Copure ® SAX is a silica-based strong anion exchanger. Its quaternary ammonium ligand is always positively charged and engenders very strong anion exchange capacity. SAX is able to extract acidic compounds such as carboxylic acids.


  • Very strong anion exchange interaction with acidic compounds
  • Capable of retaining compounds that elute from weak anion exchange sorbents
  • Simple retention mechanism, with minimal secondary interactions


Surface area: 510 m 2/g
Particle size: 40 - 75 μm
Pore size: 70 Å


  • Removal of negatively charged substances such as organic acids, nucleotides, sulfonic acids and inorganic anions from samples
  • Determination of hormones in meat
  • Determination of sulfonylurea herbicides in soil, vegetables and cereals
