Ion-Exchange SAX SPE Cartridges

Mechanism of action: SAX
Particle size: 40-75μm
Average pore size: 70 Å


Description of Strong Anion Exchange (SAX) SPE Cartridges

The strong anion exchange (SAX) solid phase extraction (SPE) cartridges are a quaternary ammonium bonded phase of the silica matrix, which is always positively charged in the full pH range and has a strong anion exchange capacity. Ion-exchange SAX SPE cartridges are ideal for extracting weakly acidic compounds such as carboxylic acids.

Characteristics of Strong Anion Exchange (SAX) SPE Cartridges

Single separation mechanism, no secondary interaction
Flexible selectivity by adjusting the solvent


Separation of proteins, peptides, phenols, nucleic acids, nucleotides and surfactants
Remove anions from the sample, such as organic acids, nucleotides, sulfonates, inorganic anions
Detection of hormone residues in meat products
Detection of sulfonylurea herbicides in soil, vegetables, and cereals
