Beyond isotopes, a complete geochemical platform

IsoFind covers the entire geochemical chain: measurement, speciation, transport modelling, source identification and report writing. Every module has been designed from real-world field and laboratory cases.

3D hydrogeochemical simulation

Model reactive transport of contaminants in the subsurface with an engine coupling advection, dispersion, non-linear adsorption, precipitation and redox speciation. Compare up to ten scenarios on the same scene to test your hypotheses.

Reactive transport 15 subsurface templates 8 stratigraphic lithologies Rayleigh coupled to concentrations Multi-hypothesis

Certifiable FAIH reports

Generate reports structured according to the FAIH philosophy (Factual, Analytical, Interpreted, Honest) via a drag-and-drop editor. SHA-256 sealing, timestamped audit trail, PDF or ISOF export, preconfigured templates for laboratories, consultancies and legal expertise.

Industrial traceability and anti-counterfeit

Identify the geographic origin of an ore, detect a blend or substitution in a supply chain, reconstruct the original signature through industrial transformations. Designed for critical materials due diligence and Critical Raw Materials Act compliance.

Molecular catalogue and elemental geochemistry

156 referenced molecules (PFAS, pesticides, PAHs, PCBs, dioxins, pharmaceuticals, forensic isomers) with their regulatory thresholds, coupled with elemental concentrations (As, Sb, Fe, Mn, Ca, Mg) and physico-chemical parameters (pH, Eh, T, conductivity, salinity) within a unified redox speciation model.

Reconstruct the origin, even after transformation

The challenge of critical raw materials traceability: the isotopic signature of an ore changes during refining and industrial transformation. IsoFind reconstructs the original signature from the final one, walking back through every step of the industrial chain.

Source signature Mine, deposit δ¹²³Sb = +0.32 ‰ Natural fingerprint Refining Industrial transformations Smelting, alloying, blending Isotopic fractionation Δ‰ added at each step Measurement Final signature Finished product δ¹²³Sb = +0.58 ‰ Modified fingerprint IsoFind reconstruction IsoFind Quick Match + Geochem ML

IsoFind inverts the fractionation calculation at each industrial step to recover the original signature, then matches it against a reference database of known deposits. This unique market capability is the core of the Quick Match Pro module.

Non-limiting examples. IsoFind is designed to handle any element or molecule whose isotopic signature can be measured, and adapts to your specific matrix.

Sb

Antimony

Flame retardants · Munitions · Semiconductors

Antimony is one of the most strategic elements on the CRM list, with over 80% of supply controlled by China. IsoFind certifies the origin of an antimony batch and detects substitution within a European supply chain.

Cu

Copper

Electrification · Cabling · Renewable energy

A central metal of the energy transition. IsoFind distinguishes copper refined from primary ore from copper sourced through recycling, and identifies multi-source blends in material flows.

W

Tungsten

Cutting tools · Carbides · Defence

One of the four conflict minerals (3TG) regulated by the EU Conflict Minerals Regulation. IsoFind contributes to supply chain due diligence by distinguishing ores from high-risk zones.

Regulatory compliance

IsoFind reports are structured to meet the requirements of the main European and international frameworks.

CRMA (EU) Critical Raw Materials Act, traceability of strategic materials
EU Battery Regulation Battery passport, supply chain due diligence

ISOF: the open standard for isotopic data exchange

ISOF (Isotopic Secure Open Format) turns scattered spreadsheets into verifiable scientific assets. Each file embeds its data, analytical metadata and cryptographic proof of integrity.

ECDSA signature Each file is digitally signed by the issuing laboratory. Any tampering is detectable without a third-party server.
Complete analytical metadata Raw ratios, uncertainties, purification yields and protocols in an immutable, reproducible container.
100% offline, MIT licensed Verification without a network connection, integrable into any LIMS. Available in Python and Rust.
Our philosophy

Built for sovereignty, not for the cloud

In a sector where data drives critical decisions, IsoFind starts from a simple principle: your data belongs to you, and should never leave your environment without your explicit consent.

100% local storage

All your data is stored on your own machine or infrastructure. No copy is transmitted to an external server, no automatic synchronisation, no dependency on a third-party service.

Zero data collection

IsoFind collects no usage data, no telemetry, no usage statistics. What you analyse remains strictly confidential, without exception.

Air-gap compatible

IsoFind runs fully on isolated networks. No internet connection is required for full use, including cryptographic verification of ISOF files.

Cryptographic integrity

Each data file can be digitally signed via ECDSA. Any tampering is detectable on opening, without a network request, ensuring a defensible chain of custody.

Open format, no lock-in

The ISOF format is published under the MIT licence. Your data remains readable and verifiable independently of IsoFind, by any system or laboratory worldwide.

Data sovereignty

Designed for sensitive environments (defence, critical industry, confidential research) IsoFind meets digital sovereignty requirements without functional compromise.

IsoFind contains no trackers, no advertising, no hidden subscription.

Knowledge Hub: understanding isotopes without prior training

Isotopic traceability rests on a demanding science. This hub gathers high-level accessible articles so that any stakeholder (industrial, legal, public decision-maker or site manager) can understand the stakes, methods and limits of the isotopic approach.

24 articles organised into 6 thematic pillars, from concrete use cases to scientific foundations.
