Dionex™ IonPac™ AS4A-SC IC Columns

Catalog number: 043174
Have Questions?
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.
