Dionex Easion IC System: A simple IC instrument for everyday ion analysis

Maintain low operating costs for your day-to-day ion chromatography analyses with the Thermo Scientific Dionex Easion ion chromatography (IC) system. This integrated, dual-piston, isocratic ion chromatography instrument is designed for labs performing day-to-day IC analyses. Small in size, but big in value, the system’s advanced technology, innovative design and intuitive software make it easy, even for new operators, to get high-quality ion chromatography results at the right price for either anion or cation analysis.


Quick and easy setup
When you purchase a Dionex Easion IC system, you get everything you need to have your ion chromatography instrument up and running in about 90 minutes, including columns, a suppressor, and eluent and regenerate concentrates. No additional pumps or equipment are required.

Simple operation and maintenance
The simple design of the Dionex Easion IC system enables easy access to its components. There are no extra items to change or maintain. Additionally, our preconfigured analysis kits take the guesswork out of system configuration for anions or cations.

Inert, reliable components

Inert, nonmetallic PEEK components throughout this ion chromatography instrument ensure compatibility with corrosive eluents and analyses free from metal contamination. The dual-piston PEEK pump is engineered to handle corrosive IC eluents and reduce maintenance costs.

Autosampler compatibility

The Dionex Easion IC system is compatible with both our Thermo Scientific Dionex AS-DV and Thermo Scientific Dionex AS-AP autosampler models, with the Dionex AS-DV recommended for walk-away convenience and built-in sample filtration.

Membrane-based chemical suppression

Worry-free, membrane-based chemical suppressors, included with the system, increase analyte signal while decreasing background noise by removing conductive ions from the eluent. They ensure maximum uptime and reduce baseline drift to minimize sample-to-sample variability.

CDS Software

The Dionex Easion IC system comes with the easy-to-use Thermo Scientific Chromeleon Chromatography Data System (CDS). This software platform provides client-server architecture and industry-leading network failure protection in addition to eWorkflows that make all our essential applications easily accessible.
