ChemSage: A powerful analytical tool for research and industry

"Powerful, versatile, easy-to-use and sure to converge - that is how our users described ChemSage."

ChemSage is a powerful analytical tool for research and industry. Its comprehensive calculation capabilities can be used to investigate a wide range of technical problems and save many hours of work compared with the use of more conventional approaches. ChemSage and its predecessor SOLGASMIX are used in many hundreds of universities, corporate and government laboratories worldwide to obtain results reliably, quickly, and efficiently. 
ChemSage is a direct descendant of the widely used SOLGASMIX Gibbs energy minimiser program developed by Gunnar Eriksson at Umea University nearly 30 years ago. ChemSage was first released in 1987 and represented a significant development of the original program. In combination, the two programs have the greatest frequency of quotation in the technical literature. The ChemSage 'engine' also forms the basis for a number of other similar software programs.

ChemSage has an excellent reputation for fast, reliable convergence of equilibrium calculations. It has been continuously refined by Gunnar Eriksson and co-workers. A regular upgrade schedule has ensured that new technical features were continuously added.

The last official version of ChemSage (V4), incorporated among other enhancements "Two Dimensional Phase Mapping" (i.e. the calculation of phase diagrams), stoichiometric reaction calculations, and a data assessment module.

ChemSage is now being used by Gunnar Eriksson as a test bed for the continued development of technical features, especially in phase equilibrium and phase diagram calculations and for the incorporation of new Gibbs energy models.

Until the final release of the data assessment module (Optimizer) in FactSage we also recommend the use of the ChemSage optimizer module. The new module in FactSage will be data compatible with the ChemSage module. A user will thus be able to simply „move on“ to FactSage when this module becomes available.
