Separate haloacetic acids and bromate in drinking water samples with high sensitivity using the Thermo Scientific™ Dionex IonPac AS26 column. Detect low μg/L (ppb) levels of haloacetic acids by using this high-capacity hydroxide-selective anion-exchange column for second dimension separation in the two dimensional IC (2D-IC) method.
Optimized for 2D-IC Determination of Haloacetic Acids
The Dionex IonPac AS26 Capillary Column is specifically designed for second dimension separation of haloacetic acids in drinking water after first dimension separation using columns such as the Thermo Scientific™ Dionex™ IonPac™ AS24A 4x250mm column. The column can also be used for determination of trace bromate, and is ideal for development of specialized applications using Reagent-Free Ion Chromatography (RFIC™) systems with gradient elution.
Reduces Operating Costs- The capillary and microbore formats require less eluent, thereby reducing operating costs
- Superior Chromatographic Performance
- Optimized for hydroxide mobile phases
- High capacity: 250μeq per column (4x250mm)
- Determines haloacetic acids in high-ionic-strength matrices without sample pretreatment in 2D-IC
- Can be operated at ambient or elevated temperatures; selectivity optimized for a 15ºC operating temperature
- Compatible with HPLC organic solvents
