The Dionex ERS 500 suppressor is a direct replacement for the Thermo Scientific™ Dionex™ SRS™ 300 Self-Regenerating Suppressor. The Dionex ERS 500 suppressors have the same fit, form and function as the Dionex SRS 300 suppressors; they have been designed to directly address all the applications currently addressed by the Dionex SRS 300 suppressors.
The Dionex ERS 500 Electrolytically Regenerated Suppressor serves virtually all analytical scale1 IC applications for both anions and cations. For anions, the preferred eluent is hydroxide. With Reagent-Free™ Ion Chromatography (RFIC)systems, the sample is determined using conductivity detection in the lowest possible background of high-purity water. AutoSuppression means ease of use; you don’t need to make regenerant because the suppressor is constantly regenerated by the continuous electrolysis of water.
