Dionex Corporation Home


Dionex products are used extensively for chemical analysis, sample preparation, and laboratory automation in the environmental, proteomics, life science/biotechnology, chemical, petrochemical, power generation, pharmaceutical, and electronics industries. Our customers include many of the world's largest companies, government agencies, research institutions, and universities.


Scientists monitor impurities in drinking water, ground water, and wastewater at trace levels. Pollutants, such as ionic and non-ionic compounds, are evaluated using Dionex technology according to regulations established by the U.S. Environmental Protection Agency and other institutions throughout the world.

Life Sciences

The study of genomics, proteomics, glycomics, and metabolomics has always been challenged by the intricacies and complexities of biological matrices. Dionex has special separation tools for proteins, peptides, oligonucleotides, oligosaccharides, and many small biomolecules to help you extract useful information out of the most challenging matrices.


From drug discovery through development into manufacturing and QA/QC, chromatography plays an essential analytical role. Whether the product is a small molecule drug, a recombinant therapeutic protein, or a vaccine, Dionex’s HPLC, IC, sample preparation, and PAT have been designed to support your fastest development cycles and highest product quality.


From the R&D through to production of BioPharmaceutical therapeutics, Dionex system solutions provide scalability and analytical efficiency.


Dionex has expanded its applications well beyond the original focus of anions and cations to include a broad range of proven HPLC separation technologies for chemical analysis, sample preparation, and laboratory automation


The end-products of the electronics industry are critical components of computers, satellite communications, telephone networks, missile guidance systems, consumer electronics, and medical instruments. Dionex instrumentation and applications play a key role in the yield and reliability of these components.


Ion chromatography (IC) is a fundamental technique for monitoring water quality for the power industry with respect to corrosive ions. Anions, cations, transition metals, silica, and boron can be monitored in raw water, demineralizer influent/effluent, process steam, boiler feedwater, boiler blowdown water, high & low pressure steam condensate, and condensate polisher water.
