Next Generation Ion Chromatography Suppressor Introduced

Thermo Fisher Scientific introduced the Thermo Scientific™ Dionex™ ERS™ 500 Electrolytically Regenerated Suppressor which replaces the Thermo Scientific™ Dionex™ SRS™ 300 Self Regenerating Suppressor. The Dionex ERS 500 Suppressor minimises dispersion to deliver higher resolution separations, especially when coupled with Thermo Scientific™ Dionex™ 4µm based IC columns. The Dionex ERS 500 suppressor permits improved compatibility with a wider range of detection techniques including MS, ICP, ICP-MS due to its improved backpressure resilience. Additionally, the Dionex ERS 500 suppressor precludes the need for periodic chemical regeneration, allowing for greater ease of use and reproducibility.

Eluent suppression technology allows for a wide variety of inorganic and organic analyses for ion chromatography applications such as environmental, high purity water, semiconductor, high purity chemicals, food and beverage, pharmaceutical and process monitoring. Suppression greatly enhances signal-to-noise ratio by decreasing the background conductivity of the eluent and associated noise while simultaneously increasing analyte conductivity. 

The Dionex ERS 500 is an electrolytic suppressor with a new hardware design that allows the suppressor to be more pressure tolerant than previous generation suppressor devices.  The suppressor flow pathway has been redesigned to optimise band dispersion and improve the flow and sealing properties.
