Dionex™ IonPac™ AS22 Fast IC Columns

Super Fast Analysis of Inorganic Anions and Low Molecular Weight Organic Acids in Diverse Matrices

• Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
• Super-fast isocratic separation of common inorganic anions in less than 5 min in diverse matrices such as drinking water, surface water, groundwater, and wastewater
• Sufficient capacity to maintain resolution even in a short column format, which helps laboratories achieve higher productivity and increased throughput
• Excellent resolution of the carbonate peak away from the common inorganic anions
• Faster alternative, using carbonate/bicarbonate eluents, for Dionex IonPac AS4A-SC, AS12A, AS14, AS14A and AS22 inorganic anion applications.
• Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.

Multiple Formats Available for Application Flexibility

• 4x150mm, 2x150mm analytical columns
• 4x30mm, 2x30mm guard columns
• Shorter 150mm columns produce faster runs of relatively clean matrices
• Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs

Note: For simple, accurate eluent preparation, use the Dionex IonPac AS22 Eluent Concentrate.
