Suppressors remove conductive ions from the eluent, thereby increasing analyte signal while simultaneously decreasing background signal and noise. They therefore enable the highest sensitivity and lowest detection limits possible for the determination of inorganic analytes by conductivity detection.
Select your suppressor of choice depending on which 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.
This next-generation suppressor delivers high capacity, low noise, high backpressure resiliency, and fast startup to meet today's demands in ion chromatography. The latest electrolytic suppressor operates in constant voltage mode, in which it can self-governs electrical current. It also operates in the traditional constant current mode. A true workhorse, this suppressor serves virtually all analytical scale IC applications.
This electrolytically regenerated suppressor is designed specifically for external water mode applications. It is compatible with solvents up to 40%, borate eluents and destructive detectors such as MS and PCR.
Get higher sensitivity and lower noise for your anion separations with a suppressor designed for anion exchange chromatography using carbonate-based eluents.
Reduce background baseline conductivity for capillary ion separations without the need for regenerant solutions with the Thermo Scientific™ Dionex™ CES™ 300 Capillary Electrolytic Suppressor.
Lower your ion chromatography (IC) detection limits with low-noise using Thermo Scientific™ Dionex™ CRS™ 500 and ACRS-ICE 500 Chemically Regenerated Suppressors. In a choice of 2, 4mm formats, the Dionex CRS 500 suppressor's high capacity and solvent compatible design can handle high complex sample matrices. The Dionex ACRS-ICE 500 suppressor is ideal for 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.
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.
