Java versions

• Due to a clash of software names, the two main programs have been renamed to "DataBase" and "Spana" (in Swedish "spana" means explore, watch, investigate).

• Advantages: java programs work on Mac OS, Unix/Linux (for example Ubuntu) and Windows systems.

• To install: download a zip-file, or the Windows "setup" file, as indicated in the Download page.

  • If you have Java properly installed, you may double-click on a "jar"-file and the program will be launched.

• This software now uses only the HALTAFALL algorithm to calculate chemical equilibrium compositions.

• In "DataBase" you may now select a temperature (if data are missing in the database, you will not be able to use this feature).

• In "Spana" it is possible to select the SIT-model for activity coefficient calculations.

• The source code may be downloaded at  GitHub.

• See also Chimera to import Phreeqc databases.

• Note: These are "beta" versions of the programs; they have been tested, but they might still have some bugs.

• For the course  KD1280 (chemical analysis) at KTH (the Royal Institute of Technology at Stockholm) there is another version with special settings and a different database. It may be dowloaded here.
