IC and Reagent-Free IC Solutions

Laboratories using RFIC* systems spend less time on equilibration, calibration, method verification, troubleshooting, and consistency checks because the systems minimize variations in the preparation of eluents and regenerants. Dual IC solutions can double throughput or increase sensitivity in complex matricies. HPAE-PAD is a sensitive, reliable technique for carbohydrate determination.

IC and Reagent-Free IC Modules

Thermo Fisher Scientific offers a wide variety of autosamplers, injectors, pumps, thermostatted column compartments, and detectors. Whether you require a dedicated system or full modularity for flexible applications, all components are integrated and single-point controlled through the Thermo Scientific Dionex Chromeleon software or easy-to-use TTL control.
