The Geochemist's Workbench 10.0 Essentials edition makes quick work of some of the tasks most commonly encountered in geochemistry. With a few mouse clicks, you can balance reactions, figure equilibrium constants, and produce Eh-pH (Pourbaix) and activity diagrams. The package features a spreadsheet designed to hold and manipulate your geochemical data.

Program GSS is the Geochemist's spreadsheet, designed to hold and manipulate your chemical analyses. Paste in your data and you can:

  • Convert chemical units.
  • Compute mineral saturation, gas fugacity.
  • Check for charge balance and figure TDS.
  • Figure aqueous species distribution, redox state.
  • Compare replicates and check standards.
  • Produce time series, cross plots, and ternary plots.
  • Make Piper, Stiff, Durov, ion balance diagrams.

And much more. Still keeping your analyses in Excel?

Programs Act2 and Tact produce diagrams showing areas of predominance for aqueous species, and stability ranges of minerals and gases. Set as axis variables:

  • Eh and pH, including Pourbaix diagrams.
  • Aqueous species activity.
  • Gas fugacity.

You can also make:

  • Solubility diagrams.
  • Mosaic diagrams.
  • Temperature-activity diagrams.

SpecE8 calculates the distribution of mass among aqueous species. Use the program to:

  • Figure concentrations, activities, activity coefficients.
  • Calculate mineral saturation states, gas fugacities.

Program Rxn balances chemical reactions. You can:

  • Balance reactions among aqueous species, minerals, and gases.
  • Calculate equilibrium constants—log Ks.
  • Figure equilibrium equations.
  • Determine equilibrium temperatures.

TEdit is a graphical editor for creating and modifying thermodynamic and surface reaction datasets. You can:

  • View and edit data tables, elements, species, reactions, log Ks, and virial coefficients.
  • Add, delete, sort, or copy and paste entries.
  • Rebalance reactions and recalculate log Ks.
  • Exchange the location of basis, redox, and aqueous species.
