Products.
Software.
Dionex developed the "Chromeleon" brand of chromatography software. The primary function of Chromeleon is to control and obtain data from analytical instruments, such as GC, LC, IEX and MS. Chromeleon is fully Title 21 CFR Part 11 compliant. Chromeleon 7.3 is the latest edition of the software.
Hardware.
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.
