Unit Size: Each 1
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 13 min in drinking water, wastewater, food & beverages, scrubber solutions, and other diverse sample matrices
• Superior retention and quantification of fluoride, glycolate, acetate, and formate
• Compatible with a sodium tetraborate 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, 2x250mm analytical columns
• 4x50mm, 2x50mm guard columns
• Longer 25mm 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 AS14 Eluent Concentrate for simple, accurate eluent preparation.

FAQs

Question: Is this a guard or analytical column?

Answer:It is a 2 mm × 50 mm guard column.

Question: What mobile phase is used with the AS14 chemistry?

Answer:The AS14 separation uses carbonate/bicarbonate eluent.

Question: What is the guard column's function?

Answer:It protects the corresponding analytical column against contaminants while maintaining AS14 separation chemistry.

Application Note

Dionex™ IonPac™ AS14 IC Columns is designed for guard-column protection during carbonate/bicarbonate ion chromatography of inorganic anions. This exact configuration is a 2 mm internal-diameter, 50 mm long guard column rather than the 250 mm analytical version. The AS14 anion-exchange chemistry supports fast isocratic separations in environmental and other aqueous matrices, including methods measuring fluoride and other common inorganic anions. Positioned before the matching 2 mm analytical column, the guard intercepts sample-derived contamination and strongly retained components that would otherwise shorten analytical-column performance. The guard uses the same AS14 separation family as the main column, maintaining method selectivity while adding a replaceable protective bed. The 2 mm geometry makes it appropriate for the corresponding small-bore ion chromatography flow path and carbonate/bicarbonate mobile phase. It is a chromatography consumable for analytical protection, not a stand-alone sample collection or membrane filtration device. Its defined 50 mm length helps distinguish this version from longer AS14 analytical formats and the wider 4 mm guard option.
