Separate inorganic anions and oxyhalides in simple matrices using an isocratic carbonate/bicarbonate eluent with the Thermo Scientific™ Dionex™ IonPac™ AS9-SC Carbonate Eluent Anion-Exchange Column. The Dionex IonPac AS9-SC column is specified in US EPA Method 300.0 (B), and meets or exceeds the performance requirements of this method. However, the advanced, high-capacity Dionex IonPac AS23 Carbonate Eluent Anion-Exchange column is recommended for determination of oxyhalides and inorganic anions, such as trace bromate, in ozonated drinking water.
Fast Separation of Inorganic Anion and Oxyhalides in Simple Matrices
- Compliance monitoring of common anions and oxyhalides in drinking water as specified in U.S. EPA Methods 300.0 (B)
- Simple, isocratic separation of inorganic anions in less than 10 minutes in drinking water
- Fast isocratic separation of inorganic anions and oxyhalides in ozonated drinking water matrices
- Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.
