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.

1When installed outside the heated column enclosure, all suppressors can support applications up to 60 ˚C.
2Solvents for anion eluents include methanol. Solvents for cation eluents include acetonitrile and dioxane.
3EWM = external water mode; for eluents containing >40% solvent, use the chemical regeneration mode.
4Recycle recommended for aqueous applications without solvent.
The SRS 300 is compatible with Dionex IC systems equipped with a suppressor power supply. The new SRS 300 products directly replace the SRS ULTRA II. Simply install the new SRS 300 into your current Dionex IC system.
