What is the purpose of the element database ELEM?
If you are using the FACT or SGPS compound database you have no need for the ELEM element database. In order to avoid uneccessary duplication of species we recommend that you remove ELEM from your calculations. Some of the FactSage modules (Reaction, Predom, EpH, Equilib, Phase Diagram) require data for the standard state elements. A user with private data (for example an imported ChemSage file) may not wish to include all the FACT or SGTE compound species in his calculations, but at the same time his limited databases may be missing the standard state elements. The ELEM database provides the necessary standard state information on the elements – the data in ELEM are taken from the FACT and SGTE compound databases (FACT and SGPS). 2.
