Eluent preparation, calibration, and equilibration take operator and instrument time away from analysis. Dionex Reagent-Free IC with Eluent Regeneration (RFIC-ER) gives you non-stop operation from one batch of eluent for up to four weeks by automatically regenerating eluent, saving time and labor. One 4L batch of eluent lasts up to four weeks.
In an ion chromatography (IC) system with eluent regeneration, effluent that would otherwise flow to waste is directed to an electrolytic device and regenerated, to be used again as fresh eluent.
RFIC-ER makes use of the electrolytic suppressor to regenerate the returning eluent. In this closed-loop system, one batch of original eluent provides non-stop operation for up to four weeks. This closed-loop system eliminates errors due to eluent preparation, provides a stable environment that does not need recalibration, and is “always ready’ for the next analysis.
RFIC-ER was developed for:
Higher injection volumes or heavy workloads may require more frequent replacement or regeneration of trap and purification columns and eluent. For applications that require hydroxide eluents or eluent gradients, RFIC-EG systems are recommended.
Day to day reproducibility is high. This data show an overlay of seven daily calibration check standards separated on a Dionex ICS-1500 RFIC-ER system using regenerated carbonate/ bicarbonate eluent.

Percent peak area changes over 28 days for a seven-anion calibration check standard separated using a 4mm Dionex IonPac AS22 column on a Dionex ICS-1500 RFIC-ER system with regenerated carbonate/ bicarbonate eluent. The system passed the daily calibration check for an entire month, requiring only one 4L bottle of eluent.
RFIC-ER is an optional configuration or upgrade for Dionex Integrion and ICS-5000+ HPIC systems.
