SAX Column Plates for Solid Phase Extraction

B&M® SAX is a strong anion exchange extraction column based on silica gel bound to quaternary ammonium functional groups. It is mainly used to extract weak-anionic compounds such as carboxylic acids. This strong anion exchanger can be used to extract negatively charged compounds from aqueous and non-aqueous solutions and is especially suitable for the extraction of weak acids. It is usually used to remove strong anions from samples (organic acids, nucleotides, nucleic acids, sulfonates, inorganic salt ions, etc.), desalination of biomolecules, etc.
