Dionex Inuvion IC System

Dionex Inuvion IC System: Ultra-reliable, day-to-day ion analysis

Perform ion analysis with the Thermo Scientific Dionex Inuvion IC System, an intuitive, ultra-reliable ion chromatography (IC) instrument with straightforward operation and extended application capabilities. This system supports electrolytic suppression and can include Reagent-Free IC (RFIC) eluent generation for additional time-savings, greater day-to-day consistency, and gradients to optimize methods. It offers automated start-up and shut-down routines to save time and consistently reliable performance for busy analytical testing laboratories.

Highlights

Flexible, adaptable platform

The Dionex Inuvion IC System is designed to help your lab meet the needs of today and the future. Upgrade the Dionex Inuvion IC System to include RFIC for automated eluent generation capabilities. Optional accessories can be swapped in and out of the instrument by users in less than five minutes for extended application capabilities.

Ultra-reliable performance

This state-of-the-art ion chromatography system is engineered for maximum productivity. With new pump technology and electronics, the Dionex Inuvion IC System provides enhanced day-to-day reliability. System self-diagnostics also detect any issues with hardware and consumables, giving you the confidence that it will be ready to run whenever you are.

Easy-to-use platform

The Dionex Inuvion IC System is designed for fast startup and maximum uptime. With convenient, unobstructed access to all necessary components and a logical flow path, users can quickly and safely access everything on the instrument.

Suppression compatibility

The Dionex Inuvion IC System offers the choice of using either chemical suppression, for more challenging samples, or electrolytic suppression, for ease of use and convenience. Suppressors remove conductive ions from the eluent to decrease background conductivity, while enhancing analyte signal, enabling high sensitivity to achieve low detection limits with conductivity detection.

High-pressure operation

With the ability to operate at up to 5,000 psi, the Dionex Inuvion IC System can take advantage of high-performance 4 µm-particle-size Thermo Scientific Dionex IC columns for more efficient separations that can be used to shorten run times.

Chromatography data system

The Dionex Inuvion IC System comes with the easy-to-use Thermo Scientific Chromeleon Chromatography Data System (CDS). This CDS platform automates and optimizes daily tasks and helps even inexperienced users achieve consistent, high-quality results.
