For fast, isocratic separation of inorganic anions in environmental waters, the Thermo Scientific™ Dionex™ IonPac™ AS4A-SC column was the preferred column for many years. It was first introduced in 1984 and is the specified column in U.S. EPA Method 300.0 (A). However, the advanced, high-capacity Dionex IonPac AS22 Carbonate Eluent Anion-Exchange column is recommended for fast analysis of inorganic anions in diverse matrices when using carbonate eluents.
Fast Isocratic Separation of Inorganic Anions in Simple Matrices
Compliance monitoring of common anions in drinking water as specified in U.S. EPA Methods 300.0 (A)
Separation of common inorganic anions in 10 minutes in water, food and beverages, and other diverse sample matrices
Compatible with sodium tetraborate gradient to optimize difficult separations
Solvent compatibility for easy column cleanup after the analysis of samples with hydrophobic components
Multiple Formats Available for Application Flexibility
4×250mm, 2x250mm analytical columns
4×50mm, 2x50mm guard columns
Longer 250mm 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
Note: Use with the Dionex IonPac AS4A Eluent Concentrate for simple, accurate eluent preparation.
