Analyze trace levels of bromate and other oxyhalides in drinking water, groundwater, wastewater, and a variety of other matrices using Thermo Scientific™ Dionex™ IonPac™ AS23-4µm columns. The column's high capacity and selectivity facilitate the determination of trace bromate at low µg/L levels in the presence of large amounts of chloride, sulfate, and carbonate. Compared to Dionex IonPac AS23 columns, the new Dionex IonPac AS23-4µm columns use smaller resin particles to improve separation efficiency, resulting in more accurate peak integration and more reliable results.

Compared to Thermo Scientific™ Dionex™ IonPac™ AS23 columns, these columns use smaller resin particles to improve separation efficiency, resulting in more accurate peak integration and more reliable results.

Designed for trace bromate analysis in drinking water

Dionex IonPac AS23-4µm is suitable for use in a variety of matrices including drinking water, groundwater and wastewater.
High capacity for routine drinking water analysis without sample pretreatment or preconcentration.
Compared with Dionex IonPac AS23 column, column efficiency and resolution are improved.
Easily transfer applications from Dionex IonPac AS23 columns to AS23-4µm columns due to similar selectivity.
Compatible with organic solvents to enhance analyte solubility, change column selectivity, and facilitate effective column cleaning.

For use with high-pressure IC systems

By using smaller resin particles, higher resolutions can be achieved and generate over 3000psi at standard flow rates column back pressure. Running this column under standard conditions and taking advantage of high flow rates and short run times requires a high-pressure IC system, such as a Thermo Scientific™ Dionex™ ICS-5000⁺ HPIC™ or Thermo Scientific™ Dionex™ Integrion™ HPIC™ System.

Available in various sizes

4 x 250 mm and 2 x 250 mm analytical columns
4x50mm and 2x50mm guard columns< /li>

Note: Dionex AS23 concentrated eluent is suitable for simple and accurate eluent preparation.
