Bring isotopic data, geochemistry, traceability, R, Python, PHREEQC and reproducible workflows together in one open environment, sovereign and offline.

Essential is free forever for research and teaching. Windows, Linux version coming soon.
These twelve systems are the ones whose isotopic fractionation is modelled natively. Any other isotope can be supported in IsoFind, and on the geochemistry side, every element and every molecule already is.
A spreadsheet for the data, a script for the calculations, another piece of software for the geochemistry. Every hop between tools loses context, and sometimes the trace of the method itself.
A number in a file says nothing about its uncertainty, its purification yield or its protocol. A year later, nobody remembers how it was obtained.
Sending sensitive measurements to an online service is often impossible, for contractual reasons as much as regulatory ones, or simply for sovereignty.
IsoFind brings these three moments of scientific work into a single environment, on your machine, locking nothing in.
Volumetric reconstruction of a plume by interpolation, with cutting plane and time slider.
Carry on running your Python and R scripts directly on your data, without rewriting them or switching tools.
Speciation, reactive transport and isotope signatures in the same environment, instead of making two programs talk to each other.
Every result leaves as an open, signed file that carries its method with it, verifiable by a third party, even ten years from now.
A platform is only worth something if you can leave it. The plugin system is not a promise: R and PHREEQC are already two of them, free and available. Every brick exists so that your data and your methods stay yours.
Your results live in an open, signed file, readable without IsoFind. MIT licence.
Extend the platform to your needs. Two free plugins already ship, others come from the community.
Built-in console: your statistical scripts run straight on your datasets.
Model speciation and geochemical equilibria without leaving your environment.
Work with your data from your notebooks, using the isof package published on PyPI.
Plug IsoFind into your processing pipelines, your LIMS and your internal tools.
Import your existing tables without reformatting them by hand.
Runs on a fully isolated machine, with no connection and no remote account.
No data leaves your machine, no telemetry is sent back, and if you walk away from IsoFind one day, your files stay readable without it. No tracker, no advertising, no hidden subscription.
The isotope signature of an ore shifts during refining and transformation. IsoFind reconstructs the original signature from the final one, walking back through every step of the industrial chain.
IsoFind inverts the fractionation calculation at every industrial step to recover the original signature, and compares it against a reference database of known deposits. This is the core of the Quick Match Pro module and of the IsoSupply edition.
ISOF (Isotopic Secure Open Format) is the exchange format shared by every edition. A file signed by a laboratory can be verified free of charge by any Essential user, with no third-party server and no network connection. A colleague, a client or an auditor can check it without owning IsoFind.
Each file is signed by the issuing laboratory through its X.509 certificate. Any alteration is detectable without a third-party server.
Raw ratios, uncertainties, purification yields and protocols inside an immutable, reproducible container.
Verification without a network connection, embeddable in any LIMS. The isof package is published on PyPI, available in Python and Rust.
We work with recognized institutions to underwrite the reliability of our analyses and our methods.
Method drawn from publications in isotope geochemistry, including an invited review in 2026.
Public specification under the MIT licence, Python package on PyPI. See it on GitHub
Reports are structured to meet the main European and international frameworks.
Seven editions built on a common core, each matched to a profession. Three ship today, the four vertical editions follow in 2026 and 2027.
24 articles organized into 6 thematic pillars, from the concrete use case to the scientific foundations. Around 10 minutes of reading per article.
isof Python package reads and verifies any file without IsoFind. The software itself depends on no server and no online infrastructure: nothing can deactivate it remotely on your machine, neither the disappearance of the vendor nor a commercial decision. No captive format, no vendor lock-in. See the code on GitHub
