Dionex Corporation is an American company based in Sunnyvale, California. It develops, manufactures, sells, and services chromatography, ion chromatography and extraction systems for separating, isolating, and identifying the components of chemical mixtures. Such equipment is used in medical research, environmental monitoring and food testing.
Dionex developed the Chromeleon brand of chromatography software. The primary function of Chromeleon is to control and obtain data from Dionex analytical instruments although the software supports instruments from other vendors. Chromeleon 7 is the latest edition of the software.
The technology made by Dionex includes the Rapid Separation LC (RSLC) and polymeric HPLC columns, a type of monolithic HPLC column. Unlike the inorganic silica columns, the polymer monoliths are made of an organic polymer base. Dionex, traditionally known for its ion chromatography capabilities, has led this side of the field. Dionex first acquired a license for the polymeric monolith technology in the 1990s. Dionex also acquired ESA Biosciences' HPLC assets in 2009, expanding its expertise in this area.
