Dionex™ IonPac™ AS24 Analytical & Guard Columns (Thermo Scientific™)

Separate haloacetic acids and bromate in drinking water samples with the Thermo Scientific™ Dionex™ IonPac™ AS24 Analytical & Guard Columns. This high-capacity hydroxide-selective anion-exchange column was developed specifically for the separation of haloacetic acids and bromate in drinking water prior to detection with mass spectrometry. The 2x250mm format is the column specified in U.S. EPA Method 557. The capacity and selectivity of the Dionex IonPac AS24 column enables analysis of haloacetic acids in drinking water at low-μg/L (ppb) concentrations. The column is also ideal for the development of specialized applications, providing excellent separation of environmental anions including inorganic anions, oxyhalides, oxyanions, and organic acids in complex matrices.

Key Features

Superior Chromatographic Performance

Specified for U.S. EPA Method 557 (2x250mm)
High-capacity 140μeq per column (2x250mm) allows injection of complex matrices without overloading the column while maintaining excellent peak shapes for lower concentration analytes
Sample pretreatment is not required when determining haloacetic acids in high-ionic strength matrices
Can be used as second dimension column in 2D method for bromate in U.S. EPA Method 302.0 (2x250 mm)
Ideal for development of specialized applications using Reagent-Free™ Ion Chromatography (RFIC™) systems with gradient elution
Can be operated at ambient or elevated temperatures; selectivity is optimized for a 15ºC operating temperature to ensure reproducible recovery for haloacetic acids
Compatibility with HPLC organic solvents provides operational flexibility and ease of cleanup
