For fast, isocratic separation of inorganic anions in environmental waters.
Thermo Scientific™ Dionex™ IonPac™ AS4A-SC Carbonate Eluent Anion-Exchange Analytical Columns, preferred for many years after first being introduced in 1984 as the specified column in U.S. EPA Method 300.0 (A). Note: 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.
IonPac™ AS4A-SC Analytical Column Features:
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 beverage 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
