Thermo Scientific Dionex IonPac AS14A IC Columns

Deliver fast isocratic separation of inorganic anions from diverse and complex matrices such as drinking water, wastewater, foods and beverages, and scrubber solutions with the Thermo Scientific™ Dionex™ IonPac™ AS14A Carbon Eluent Anion-Exchange Column. The Dionex IonPac AS14A column meets or exceeds the requirements of U.S EPA Method 300.0 (A). However, the Dionex IonPac AS22 Carbonate Eluent Anion-Exchange column, an advanced carbonate eluent column, is recommended for fast analysis of inorganic anions. For the fastest separation of inorganic anions using a carbonate/bicarbonate eluent, the Dionex IonPac AS22-Fast column is recommended.

Fast Separation of Inorganic Anions in Diverse Matrices

• Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
• Separation of common inorganic anions in 8 min (3 x 150mm format) or 13 min (4 x 250mm format) in diverse sample matrices
• Superior retention and quantification of fluoride
• Compatible with sodium or potassium hydroxide gradient to optimize difficult separations
• Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.

Multiple Formats Available for Application Flexibility

• 4x250mm, 3x150mm analytical columns
• 4x50mm, 3x30mm guard columns
• Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
• 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: Use with the Dionex IonPac AS14 Eluent Concentrate and the Combined Seven Anion Standard for simple, accurate eluent preparation.
