Allsphere SAX is a strong anion exchange (SAX) HPLC column based on fully porous, high-purity silica and modified with quaternary ammonium functional groups. This phase provides strong electrostatic retention for negatively charged analytes such as organic acids, nucleotides, and ionic food additives. Designed for robustness and reproducibility, Allsphere SAX is ideal for ion-exchange separations in pharmaceutical, environmental, and food analysis.
Allsphere SAX delivers reliable anion exchange performance for charged analytes – ideal for targeted and routine applications involving ionic species.
