Thermo Scientific Dionex IonPac AS4A-SC IC Columns

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.
