Optimized for 2D-IC Determination of Haloacetic Acids
- Designed for separation using the Dionex IonPac AS24A 4x250mm column for the first dimension prior to using the Dionex IonPac AS26 capillary column for the second dimension
- Minimal baseline shifts and enhanced analyte sensitivity can be obtained using the Thermo Scientific™ Dionex™ Anion Self-Regenerating Suppressor (ASRS™ 300)
The Dionex IonPac AS24A Capillary column offers users excellent retention time and reproducibility in addition to increased mass sensitivity and eluent conservation.
Superior Chromatographic Performance- High capacity–560µeq per column (4x250mm)–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
- The column is 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
