Dionex™ IonPac™ AS12A IC Columns (Thermo Scientific™)

Separate inorganic anions and oxyhalides, such as chlorite and bromate, in environmental samples. The Thermo Scientific™ Dionex™ IonPac™ AS12A Analytical and Guard Columns resolve trace chloride and sulfate in high-carbonate samples and meet or exceed the requirements of U.S EPA Methods 300.0 (A) and (B). However, the advanced, high-capacity IonPac AS23 Carbonate Eluent Anion-Exchange column is recommended for determination of oxyhalides and inorganic anions, such as trace bromate, in ozonated drinking water.

Key Features

Fast Isocratic Separation of Inorganic Anions and Oxyhalides in Diverse Matrices

Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A) and (B)
Separation of common inorganic anions and oxyhalides including chlorite, bromate and chlorate in less than 12 minutes
Superior retention and quantification of fluoride
Trace analysis of chloride and sulfate in high-carbonate samples
Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.

Multiple Formats Available for Application Flexibility

4x200mm, 2x200mm analytical columns
4x50mm, 2x50mm guard columns
Longer 200mm columns facilitate higher resolution separations of more complex sample matrices
Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs
