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
