Dionex IonPac AS19 capillary columns are packed with the same materials as standard bore columns (with the same performance as 4 mm columns) but only require 1% eluent flow rate. The advantage of capillary tubes is that the amount of eluent used is significantly reduced, thereby reducing operating costs.
Excellent chromatographic analysis performance- High capacity: 240µeq per column (4x250mm)
- Can operate at room temperature or high temperature, with 30 °C optimized column selectivity
- Compatible with organic solvents
- When using Thermo Scientific™
- Dionex™ Anion Automatic Regeneration Suppressor (ASRS™ 300) and Reagent -Free™ (RFIC™) system for low background signal and enhanced analyte sensitivity
- Analysis of a variety of oxyhalides and inorganic anions
- Oxyl halides and common inorganic anions, including Fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate and sulfate in drinking water, groundwater, wastewater and various other sample matrices.
- Analyzes most drinking water without sample pretreatment or preconcentration.
- Especially suitable for use with Reagent-Free™ Ion Chromatography (RFIC)™ systems to automatically generate eluents
The primary application of this column is the determination of trace bromate in drinking water matrices using a potassium hydroxide gradient and suppression conductivity detection. The column's selectivity enables quantification of bromate at low µg/L concentrations using suppressed conductivity detection, even in the presence of ultra-high concentrations of chloride, sulfate, and carbonate. in this way.
