User Guide

The MPIC Suppression Mode is a combination of the AutoSuppression External Water Mode augmented with a chemical regenerant such as sulfuric acid (H₂SO₄). The MPIC Suppression Mode uses an applied current and a constant source of dilute sulfuric acid solution from a pressurized bottle delivery system. This mode must be used for MPIC applications requiring an ion pair reagent and organic solvents in the eluent.

The MPIC Suppression Mode reliably provides suppression of typical eluents for MPIC applications using suppressed conductivity detection. The ion pair reagents, such as tetrabutylammonium hydroxide (TBAOH), are used in concentrations typically ranging from 1.0 to 5.0 mM.

See Operation for complete operating instructions.

NOTE

The Dionex ADRS 600 and Dionex AERS 500e can be used for eluent suppression of Mobile Phase Ion Chromatography (MPIC or ion-pairing) eluents by using the MPIC Suppression Mode. MPIC Suppression Mode is not recommended on the Dionex AERS 500 Carbonate.
