Thermo Scientific Dionex IonPac AS9-SC IC Columns

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.

Formats Available for Application Flexibility

• 4x250mm analytical columns
• 4x50mm guard columns
• Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
