The Geochemist's Workbench® has from its introduction in 1991 set the standard in geochemical modeling. 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.
Already a GWB user? Your GWB 2023 subscription brings solid solutions, SIT activity coefficients, and the ChemPlugin self-linking software object included with GWB Professional at no extra charge. With the all new TEdit thermo data editor, you can import thermo datasets from PhreeqC, and import and export EQ3/EQ6 databases! An all new compute engine makes the GWB a surface chemistry powerhouse. Plus, subscribers benefit from user equations in GSS datasheets, high-temperature Pitzer coefficients, cluster computing, and flexible input for thermo data, just to start.
Using an older version of the GWB? Consider upgrading to a modern subscription.
The Geochemist's Workbench® Professional edition is the complete software package. Create spreadsheets and specialty diagrams, trace reaction models, compute complex phase diagrams, and simulate reactive, bioreactive, isotopic, and colloidal transport.
GWB Pro accounts for equilibrium and kinetic reactions in heterogeneous, dual-porosity media, including simulation of microbial metabolism and growth. Only the professional edition is multithreaded. GWB Pro lets you animate your results and create video clips in just moments.
And now GWB Pro includes ChemPlugin at no extra charge!
The Geochemist's Workbench® Standard edition is your choice for spreadsheets, diagrams, and multicomponent reaction modeling. Plot how species distributions change, model water-rock interaction, and simulate fluid mixing.
Integrate kinetic rate laws for mineral dissolution and precipitation, complex association and dissociation, sorption and desorption, redox transformation, and gas transfer. Trace stable isotope fractionation in reacting systems. Model microbial metabolism and growth, including the population dynamics and the development of community structure.
The Geochemist's Workbench® Essentials edition performs the most common tasks in geochemical modeling. With a few clicks, you can balance reactions, figure equilibrium constants, and make Eh-pH diagrams. Computing speciation, saturation, gas pressure, and isotope distributions is a snap.
The package features a spreadsheet designed for geochemical analyses. Instantly convert units or figure mineral saturation for all your samples. Create time series and cross plots, and ternary, Piper, or Stiff diagrams. Import thermo databases from PhreeqC and EQ3/EQ6. And that's just the beginning.
