+ analyte → Calculate...

Enter chemical data for one or more samples,then use GSS to calculate additional analytes.

Variable → Mineral saturation...

Calculated Mineral saturation appears below original data for each sample.

Choose minerals

CO2(g) fugacity is added to the analytes section.

Compute gas fugacities

Check for charge balance and figure TDS

Figure redox state for every redox pair

Select species

Figure aqueous species distribution

Choose samples to compare and enter error tolerance.

Compare replicate samples with themselves or with astandard. Enter data for each sample then go to Analysis...

Check marks indicate a small coefficient of variance between replicates. X's appear where the error tolerance is exceeded.

Display your data in Time Series and XY Plots

Graphs → Time Series Plot

Analyze samples using standardwater chemistry diagrams.
