Adsorbosphere XL SAX is a strong anion exchange (SAX) HPLC column built on high-purity, fully porous silica and engineered for long-term chemical stability. Functionalized with quaternary ammonium groups, this phase enables highly selective retention of negatively charged analytes, including organic acids, nucleotides, and ionized pharmaceuticals.
As part of the XL (Extended Lifetime) series, Adsorbosphere XL SAX is optimized for reproducibility and resistance to degradation in buffered aqueous systems – making it a dependable choice for routine ion-exchange separations under demanding conditions.
Adsorbosphere XL SAX combines strong anion exchange selectivity with long-lasting performance — ideal for analytical tasks where reproducibility and robustness are essential.
