Industrial Chromatography

Maximize the number of injections between eluent changes when using a Reagent-Free™ ion chromatography with eluent regeneration (RFIC™-ER) system with the Thermo Scientific™ Dionex IonPac AC-ER Anion Concentrator column. The Dionex IonPac AC-ER Anion Concentrator for RFIC-ER is a general purpose, low dead volume, extremely low pressure anion concentrator column with similar features to the Dionex IonPac UTAC Ultra Trace Anion Concentrator Columns, but with reduced dead volume and capacity. The Dionex IonPac AC-ER concentrator is housed in a 4 x 16mm column body for very low dead volume to maximize the number of injections that can be made on an RFIC-ER system between eluent exchanges.

Perform More Than 250 Injections Before Replacing the Eluent

With a Dionex IonPac AC-ER concentrator installed in an RFIC-ER system, each injection only adds 75μL of sample matrix into the eluent regardless of the sample volume (70μL + 5μL for connecting tubing). Therefore, approximately 266 injections can be performed before the eluent needs to be replaced, regardless of the actual amount of sample loaded onto the concentrator.

Bringing a Host of New Applications within Range of RFIC-ER Systems

By using a matrix elimination step with the Dionex IonPac AC-ER concentrator in place, solvents can be directly injected onto the column then flushed off before injection into the RFIC-ER system. The new Dionex IonPac AC-ER concentrator brings a host of new applications within range of RFIC-ER systems, including analysis of bromate to 5 ppb in drinking water, and analysis of common anions in ethanol.
