Dionex Corporation

What Dionex Corporation does

Dionex Corporation was founded in 1975 and headquartered in Sunnyvale, California as a pioneer in ion chromatography (IC) and high-performance ion chromatography (HPIC) technology. The company built its reputation over more than four decades around instruments and chemistries for analytical separation and detection, with the Dionex brand becoming closely associated with ion chromatography in pharmaceutical, environmental, food and beverage, and industrial analysis laboratories. Following its 2011 acquisition by Thermo Fisher Scientific, Dionex ceased to operate as an independent public company (it had previously traded on NASDAQ as DNEX) and now functions as a product line and brand within Thermo Fisher's chromatography portfolio, with the Dionex name retained on flagship products such as the Dionex ICS-6000 HPIC System and the Chromeleon Chromatography Data System (CDS).

The current product portfolio spans ion chromatography systems, HPLC and UHPLC systems (including the Vanquish Duo), gas chromatography systems (including the TRACE 1600 Series), automated sample preparation (TriPlus RSH SMART Autosampler, EXTREVA ASE), bioprocessing chromatography resins (POROS), discrete wet-chemical analyzers (Gallery), chromatography consumables (columns, vials, reagents), and software platforms (Chromeleon CDS and the Thermo Scientific Ardia Platform). Underlying technology centers on separation science — high-pressure ion chromatography, dual-LC workflows, accelerated solvent extraction, and integrated data systems that scale from research through development to QC. Notable technical components include PFAS-reducing sample prep components in the EXTREVA ASE and bioprocess capture/polish resins for biomanufacturing.

The business model combines capital equipment sales (HPLC, IC, GC instruments) with recurring consumables revenue (columns, vials, reagents, resins) and software subscriptions for Chromeleon CDS and Ardia. Pricing is not publicly disclosed. Go-to-market is conducted exclusively through Thermo Fisher Scientific's global chromatography distribution network — direct field sales, inside sales, e-commerce, and Unity Lab Services — rather than through an independent Dionex sales force. The primary customer segment is pharmaceutical and biopharma (with RSSL publicly cited as a customer for GMP testing using the ICS-6000 HPIC System), with additional reach into environmental testing, food and beverage, and oil and gas laboratories through the parent's broader chromatography channels.

Core offering

Dionex Corporation develops and manufactures ion chromatography (IC) and high-performance ion chromatography (HPIC) systems, along with HPLC, UHPLC, GC instruments, autosamplers, and chromatography data software used for analytical separation, concentration, and detection of target molecules in complex mixtures. The product portfolio under the Dionex brand is marketed and distributed by Thermo Fisher Scientific for pharmaceutical, biopharma, environmental, food and beverage, and industrial laboratory workflows.

Product overview

Thermo Fisher Scientific's chromatography portfolio under the Dionex brand offers a comprehensive, integrated workflow solution for analytical laboratories. The portfolio consists of a unified platform of chromatography instruments, software, and consumables. Core instruments include the Dionex ICS-6000 HPIC System for ion chromatography, Vanquish Duo UHPLC Systems for ultra-high performance liquid chromatography, TRACE 1600 Series Gas Chromatographs, and the TriPlus RSH SMART Autosampler for automated sample injection. The Chromeleon Data System serves as the central software platform connecting all instruments across research, development, and QC environments. Supporting products include chromatography consumables (columns, vials, reagents), sample preparation solutions like the EXTREVA ASE system, and bioprocessing chromatography resins. The portfolio is designed to provide complete workflow solutions from sample preparation through data analysis, with applications spanning environmental testing, food and beverage, pharma and biopharma, and oil and gas testing.
