2013年5月8日，戴安推出了Thermo Scientific Dionex ERS 500 系列电解再生抑制器，与此同时开始停产Thermo Scientific Dionex SRS 300 系列自再生抑制器。SRS 300 抑制器的订单将自动被对应的 ERS500 抑制器取代。受影响产品的产品号见本通知附表。Dionex ERS 500 抑制器是直接替换 Dionex SRS 300 抑制器的换代产品；与 SRS300 抑制器相比，其结构与功能并没有变化。
Dionex ERS 500 抑制器的主要优势在于：
更好的抑制器性能提供了更高的最佳效率，尤其是当该抑制器与4μm填料柱一起使用时；
更高的柱压耐受能力，能适用于更多的检测器联用技术；
更好的热稳定性，消除了因运输、处理、操作过程导致的安装故障；
完全免试剂电解再生，不需要额外的流路就可轻松实现良好的抑制重现性。

戴安 SRS 300 离子色谱 再生抑制器
High-Capacity Electrolytically-Regenerated Suppressor for Use with IC Eluents
The SRS 300 serves virtually all analytical scale1 ion chromatography applications for both anions and cations. For anions, the preferred eluent is hydroxide. With 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. The SRS 300 offers:
Low background noise levels
Fast startup equilibration times
Trace anion and cation determinations
Compatibility with mass spectrometry detection
Compatibility with all Dionex ICS and DX chromatography modules2
A three-fold increase in backpressure tolerance compared to previous generations
The SRS 300 delivers low backgrounds and low noise levels for the full range of Dionex ion-exchange IonPac columns and eluents, even under high-concentration gradient conditions.
When combined with the revolutionary Eluent Generator, The SRS 300 delivers truly automated, minimal-maintenance Reagent Free Ion Chromatography (RFIC).
1For capillary scale ion-chromatography applications use the Capillary Electrolytic Suppressor (CES 300).
2Chemical suppression mode only with the ICS-90 and ICS-900 systems. Older systems may require the RFC-10 or RFC-30 controller.
