The highest sensitivity for the lowest possible detection limits

Enable the highest sensitivity and lowest possible detection limits

The suppressor is a key component of ion chromatography (IC), as it removes conductive ions from the eluent, thereby increasing analyte signal while simultaneously decreasing background signal and noise. This means you get the highest sensitivity and lowest detection limits possible for the determination of inorganic analytes by conductivity detection.

We offer a variety of suppressor products designed to provide you with the optimal results based on the eluent, organic solvents, analyte and matrix concentration, and IC system format you use. Electrolytic suppression products based on Reagent-Free Ion Chromatography (RFIC) with AutoSuppression are available exclusively in the Thermo Scientific Dionex product catalog. Explore our full portfolio below or consult with our experts to customize a selection for your specific application and workflow needs.

Meet the growing demands of the ion chromatography market with the Thermo Scientific Dionex NGES Next Generation Electrolytic Suppressor. This suppressor provides improved backpressure resiliency and sustains accurate results with exceptional peak resolution for virtually all analytical-scale IC applications.

Lower your ion chromatography detection limits with low noise using the Thermo Scientific Dionex CRS 500 and ACRS-ICE 500 Chemically Regenerated Supressors. Available in 2 and 4 mm formats, the Dionex CRS 500 suppressor’s high capacity and solvent-compatible design can handle highly complex sample matrices. The Dionex ACRS-ICE 500 suppressor is designed for the analysis of organic acids and alcohols by ion-exclusion chromatography in food and beverage products, biological samples, fermentation processes, industrial process liquors, and treated wastewaters.

Streamline your IC carbohydrate methods with automated salt removal from high-pH eluents and effluents using the Thermo Scientific Dionex ERD 500 Electrolytically Regenerated Desalter. This desalter removes sodium ions from alkaline sodium acetate effluent in line, such as after high-performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD).

Webinar: Advances in Electrolytic Suppression for Ion Chromatography

Suppression technology is the heart of an ion chromatography (IC) system. Previous advances in suppressor functionality have focused on continuous operation, achieving high-capacity and ease-of-use. Advances in the future will continue to optimize these parameters, but will also focus on an array of other improvements, including backpressure tolerance, peak efficiency and current efficiency.
