Reagent-Free Ion Chromatography with Electrolytic Sample Preparation

Thermo Scientific™ Dionex™ RFIC-ESP systems enable a range of automated sample preparation techniques which utilize proprietary electrolytic devices to provide reduced cost and higher value analyses.

Dionex RFIC-ESP devices and techniques can remove cations from an anion sample before analysis  using a Thermo Scientific Dionex CR-TC device; or neutralize a strongly acidic or basic solution (for example, 25% phosphoric acid or  sodium hydroxide solutions) with a Thermo Scientific Dionex AutoNeutralization system. A new Electrolytic Water Purifier provides water of extremely high purity (backgrounds below part per trillion levels are possible) for use in trace-level analytical work along with a concentrator column.

RFIC-ESP Systems Provide Several Advantages:

  • Automated techniques are highly reproducible, instrument-to-instrument and lab-to-lab
  • Automated techniques are not prone to human error and inconsistencies, as are manual methods
  • Reduced manual operation results in reduced labor costs and sample processing time
  • No sample loading pump is necessary, resulting in reduced system costs
  • Ultra low backgrounds from online electrolytic water purification, permit routine ng/L level trace analysis
  • Automated purification, concentration, and calibrations all reduce labor costs and improve result quality
