Chemically-Regenerated Suppressor Optimized for Ion-Exclusion Chromatography
The Thermo Scientific™ Dionex™ ACRS-ICE™ 500 Anion Chemically Regenerated Suppressor is designed for the analysis of organic acids and alcohols in complex or high-ionic-strength samples, including food and beverage products, biological samples, fermentation processes, industrial process liquors, and treated wastewaters. This suppressor is ideally suited to ion-exclusion chromatography of organic acids and alcohols in complex or high-ionic-strength samples. It provides the following advantages:
High-capacity and solvent compatible design
Optimized for organic acid and alcohol analysis in complex or high-ionic-strength samples
Low detection limits, high signal-to-noise ratio, and excellent baseline stability
Fast startup and equilibration
The Dionex ACRS-ICE 500 suppressor is used in chemical suppression mode with a tetrabutylammonium hydroxide (TBAOH) regenerant. Standard ion suppression converts analytes into their acid or base forms. The Dionex ACRS-ICE 500 suppressor increases analyte conductivity by forming the TBA salt of the weak acid analyte, which is more conductive than the partially ionized acid form of the analyte.
The Dionex ACRS-ICE 500 suppressor removes the hydronium ion and any counterions of the analytes from the eluent stream and replaces them with tetrabutylammonium ion. This removal greatly reduces background conductivity. In addition, this mechanism forces the ionization of weak acid analytes, increasing sensitivity.
