The Geochemist's Workbench has from its introduction in 1991 set the standard in geochemical modeling. Thousands of copies have been licensed and installed in more than 90 countries around the world.
With its crisp user interface, fully integrated graphics, highly optimized algorithms, and advanced software architecture, the GWB makes quick work of geochemistry tasks small and large. With just a few clicks, GWB Community Edition balances reactions, figures equilibrium constants, and produces Eh-pH (Pourbaix) and activity diagrams. The package features a spreadsheet designed to hold and manipulate your geochemical data.
GWB Community Edition is available at no charge for everyone. Download GWB Community Edition from our community page. You'll be up and running in no time. Your license will last for a year, after which you'll need to get a new license.
The abilities of GWB Community Edition are summarized below. Paid versions offering advanced features such as reaction path simulation and reactive transport modeling are available as upgrades.
Program GSS is the Geochemist's spreadsheet, designed to hold and manipulate your chemical analyses. Paste in your data and you can:
And much more. Still keeping your analyses in Excel?
Program Rxn uses an intuitive basis swapping method to balance chemical reactions and compute reaction properties. From the concise graphic user interface, you can:
Programs Act2 and Tact produce diagrams showing areas of predominance for aqueous species, and stability ranges of minerals and gases. Set as axis variables:
You can also make:
SpecE8 calculates the distribution of mass among aqueous species. Use the program to:
SpecE8 also computes the equilibrium isotope fractionation in a geochemical system:
