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.
Dionex develops 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 latest technology made by Dionex is the Rapid Separation LC (RSLC) and the 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.
Thermo Fisher Scientific announced its acquisition of Dionex in December 2010 for $2.1 billion to develop the water sector-analysis in China.
