Publish your methods, not just your results

R Console

The full power of the R language, embedded in IsoFind through WebR. Your code runs entirely on your machine, with no R installation and no connection, with direct access to your samples and analyses. You keep full control of your data, from computation to plot.

• Four-pane RStudio-style layout: script editor, console, plots and environment, in a single window
• Interactive R console with command history, run the whole script or a selection
• R plots captured and shown directly in the dedicated pane, ready to read and export
• Multi-source dataframe builder: assemble an R object from your samples and analyses without rewriting the data
• Environment inspector and built-in help to track your objects and functions
• Named script management: save, reopen and organize your recurring analyses
• Template library of analyses, ready to adapt to your datasets

• Statistics and regressions on your isotopic series
• Custom plots for your reports and publications
• Reproducible workflows, replayed from one campaign to the next

1. Install the .isplugin archive from the Plugins tab in IsoFind. The signature is verified automatically.
2. Open the R Console from the plugins menu. On first launch, the R engine prepares locally.
3. Build a dataframe from your samples, or write your own code in the editor.
4. Run, read the output in the console and view the plots in the graphics pane.
5. Save the script under a name, or start from a template in the library.

PHREEQC Console

PHREEQC, the reference geochemical code from the USGS, embedded in IsoFind and compiled to WebAssembly. The console computes aqueous speciation, mineral equilibria and saturation indices, then turns it all into a readable interpretation, directly on your samples. All computation stays on your machine.

• Direct sample import: measured pH and Eh preserved and flagged, analyses aggregated per element
• Distribution of species in solution, as a table and log-molality bars
• Solution summary: ionic strength, charge balance, conductance, density, water activity, with a data-quality alert
• Dominant oxidation state of key elements (Fe, Sb, As, S, Cr, Mn, Se, U), with a mobility and toxicity note
• Sorted saturation indices, with a divergent precipitation-versus-dissolution chart
• Automatic interpretation: iron oxyhydroxides and oxyanion adsorption, sulfides depending on redox, carbonates and pH buffering
• PDF export of the results panel as displayed, charts included

Vary pH, pe or temperature over a range, and track how the species and the saturation indices of the chosen minerals evolve. The console detects the crossover thresholds by interpolation and reports them, for example the exact pH at which goethite becomes oversaturated. This is the direct answer to the threshold at which a precipitation or dissolution process kicks in.

1. Install the .isplugin archive from the Plugins tab in IsoFind. The PHREEQC engine and databases are embedded, nothing else to install.
2. Pick a thermodynamic database suited to your study.
3. Search a sample by autocompletion; import is automatic, measured pH and Eh preserved.
4. Run and read the interpretation, species, oxidation state and saturation indices.
5. Switch to What-if mode to track the evolution against a condition.
6. Export the result to PDF in one click.
