Description

Length (Metric): 250 mm
Diameter (Metric): 4 mm
Column Type: Analytical Column
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.

Application Note

Dionex™ IonPac™ AS14 IC Column, 4 × 250 mm is used for fast isocratic anion-exchange separation of common inorganic anions in environmental and routine analytical samples. The analytical column uses a carbonate/bicarbonate eluent system and a 9 µm ethylvinylbenzene/divinylbenzene packing carrying alkyl quaternary ammonium ion-exchange groups. Its capacity is approximately 65 µeq, with a standard-bore 4 mm internal diameter and 250 mm length. The column supports compliance monitoring of drinking-water anions under U.S. EPA Method 300.0(A) and can separate fluoride, glycolate, acetate, formate, and other inorganic anions in diverse matrices. It operates at 1.2–3.0 mL/min, supports up to 4000 psi, and is compatible with pH 2–12 and 0–100% HPLC solvents for cleanup.
