Whether you need to trace the origin of a contamination, verify the provenance of a mineral, detect a food fraud or interpret archaeological data, IsoFind turns your isotopic measurements into clear, documented answers, accessible even without deep isotopic expertise.
When a river is contaminated or a soil shows abnormal metal levels, you need to answer one simple question: where does this pollutant come from, and how is it spreading? Stable isotopes are the only tracers capable of answering that question without altering the environment. IsoFind organises the entire workflow, from raw data import to mapped results and a defensible report.
By comparing the isotopic signature of a contaminant to the fingerprints of known sources (industry, road traffic, mining activity...), IsoFind identifies the probable origin and calculates each source's contribution. Even when multiple sources mix simultaneously, isotopic unmixing quantifies each one separately.
Source apportionmentCompare signatures measured at different dates to document the effectiveness of a remediation or detect the arrival of a new source. IsoFind manages time series and visualises trends.
Temporal monitoringProject your results onto an interactive map to delineate influence zones and contamination gradients. Direct export for reports to local authorities, water agencies or regulatory bodies.
Cartographie SIGUnderstand the mechanism by which a contaminant mobilises and spreads: oxidation, dissolution, adsorption onto iron minerals, gas-phase transfer. IsoFind models the isotopic fractionations associated with each process to distinguish sources from transport vectors.
Geochemical processesCompound-specific isotope analysis (CSIA) of carbon (delta ¹³C) and chlorine (delta ³⁷Cl) allows PFAS families to be distinguished by manufacturing process, quantifies in-situ pesticide biodegradation via the Rayleigh model, and identifies sources of pharmaceutical residues in surface water. IsoFind centralises and normalises this data molecule by molecule.
Free (PFAS / Pesticides)Reconstruct the contamination plume in three dimensions from your point data by IDW interpolation. The coupled predictive engine (geochemical prior + ML ONNX) simulates the temporal evolution of the contaminant in the aquifer, accounting for speciation, adsorption and degradation. Time slider, interactive cross-section, PNG export.
Free (PFAS / Pesticides) Pro (other molecules)Combine Pb-Sb, Cu-Zn or S-O in a single discrimination space. IsoFind manages multi-dimensional display and confidence ellipses to separate sources that classical chemistry cannot distinguish.
Multi-tracersEvery processing step is automatically recorded. Generate a structured report including the cover page, geochemical conditions, ML speciation results, attribution scores and methodological limits, adapted to the requirements of environmental authorities (EPA, water agencies) and defensible in case of litigation.

Download IsoFind for free. PFAS and pesticide tracing, including 3D visualisation, is available without a licence.Every raw material carries an isotopic fingerprint tied to its geology and extraction method. When a supplier changes source without declaring it, classical chemical methods miss it. Isotopic analysis detects it. IsoFind lets you build a signature reference by supplier, compare each incoming batch and produce a certifiable conformity report.
Compare the isotopic signature of a delivered batch to the reference of the declared mine or supplier. IsoFind automatically flags any significant deviation. The answer is binary and defensible: compliant or non-compliant, backed by data. A direct response to the due diligence obligations of the Critical Minerals Act and the growing demands for supply chain transparency.
Origin conformityEvery industrial process slightly modifies the isotopic signature of a material. The Nexus module lets you visually simulate these transformations step by step, from raw ore to finished component, predicting the expected output signature.
IsoFind NexusEvery received batch is recorded with its signature. If a supplier quietly changes their supply source, the deviation from historical data is automatically detected on the next batch.
Batch monitoringEvery action is timestamped and attributed to its author: imports, edits, exports, logins. This permanent log is exportable and constitutes a defensible activity record for any certification audit or regulatory procedure.

API REST / FastAPITypical workflow in IsoFind
Secure your supply chain and automate your controls.
IsoFind Pro includes the full audit trail, database protection, multi-user management and REST API access to integrate IsoFind into your existing systems.Isotopic signatures are intrinsic to materials: they do not change over time, are invisible to the naked eye, and cannot be copied without specialist equipment. IsoFind lets you build an authenticity reference for your products and compare each sample to that reference, concluding objectively and in a documented way to either conformity or fraud.
A product cut with a cheaper material presents a mixed isotopic signature, measurable and quantifiable. IsoFind automatically detects any sample whose signature departs from the authentic product's reference, calculates the fraud probability and estimates the adulterant proportion. The conclusion is clear and backed by data.
Fraud detectionCompile signatures from your authentic products by batch, vintage or production site. IsoFind automatically calculates the statistical envelopes that define the acceptable signature of a compliant product.
Two materials of identical chemical composition but from different geographical origins have distinct isotopic signatures. IsoFind enables this discrimination where all other analytical methods fail.
For products without a sufficient natural fingerprint, IsoFind guides the design of active marking: controlled introduction of a specific isotopic ratio during manufacturing, impossible to reproduce without dedicated equipment.
Every conclusion comes with a complete record: method applied, reference used, comparison statistics, full history. Structured for presentation to a certification body or a court.

Protect your brand and your customers with scientific evidence.
IsoFind lets you build your authenticity reference and set up regular controls.IsoFind is designed by geochemists for the demands of research laboratories: management of thousands of samples with complete metadata, fractionation modelling, geochemical machine learning, GeoReM and CRM compatibility, CSIA analysis of organic molecules, predictive 3D modelling of aquifers, and a plugin system to extend analytical capabilities to your own methods.
IsoFind's ML engine, trained on millions of published geochemical data points and synthetic PHREEQC simulations, identifies geological contexts, predicts speciation and adsorption of trace elements (Cr, Fe, As, Sb...) and organic molecules (TCE, PCE, BTEX), and anticipates isotopic behaviours in different environments. Every suggestion is accompanied by its scientific justification.
Non-destructive ML Pro: speciation + adsorption ONNXStore, normalise and query thousands of samples with their complete metadata, including geochemical data, organic molecules and field physico-chemical conditions. GeoReM and CRM compatible, the database is SQLite: portable, durable and exportable in all common formats.

Community pluginsTypical workflow in IsoFind
IsoFind Research is free for public research institutions.
Access the full documentation and explore the shared community database.Food products carry an isotopic fingerprint linked to the soil, water and climate of their production area. This fingerprint does not lie. A cut, substituted or mislabelled product shows a signature that departs from that of the authentic product. IsoFind lets you build your appellation's reference and control each incoming or suspect batch.
A product diluted with cheaper oil, synthetic honey or wine from another region presents a composite isotopic signal that IsoFind automatically decomposes. The software calculates the adulterant proportion and identifies its probable nature from candidate source signatures. The conclusion is immediate, documented and exportable.
Food unmixing Detection and quantification of the adulterantOxygen and hydrogen isotopes reflect the local water signature. Carbon and nitrogen isotopes reflect the type of vegetation and agricultural practices. IsoFind compares each sample to the declared region's reference.
Each climate year leaves a specific isotopic fingerprint in plant products. IsoFind lets you progressively build your own signature database by vintage and verify, batch by batch, the concordance between the declared year and the measured signature.
Progressively compile the authentic signature base for your appellation, manage natural inter-annual variability and statistically define the limits of what is "typical" for your terroir.
Nitrogen isotopes can discriminate chemically fertilised crops from organic ones. This analysis is achievable in IsoFind via a dedicated plugin, as a complement to standard documentary controls, adding an objective analytical proof to your certification dossier.

Protect your producers and the reputation of your appellation.
IsoFind supports you from building the reference to regular batch controls, with reports adapted to certification bodies.Archaeological materials and biological remains carry an isotopic memory of their place of origin and history. This memory allows us to retrace ancient trade routes, the provenance of raw materials used by craftspeople, population migrations or authenticate works of art. IsoFind structures these analyses in a rigorous, documented and shareable framework.
Identify the geological origin of a metal, marble or clay by comparing its isotopic signature to the fingerprints of known deposits and quarries from the period. IsoFind manages provenance reference databases and calculates the probability of belonging to each candidate source, accounting for analytical uncertainty and the natural variability of deposits.
Archaeometry Geological origin identification of a materialLead isotopes (²⁰⁶Pb/²⁰⁴Pb, ²⁰⁷Pb/²⁰⁴Pb, ²⁰⁸Pb/²⁰⁴Pb) vary according to the geological age and composition of source rocks. IsoFind allows comparison of the lead signature of a metal object, pigment or glass against ancient mining and geological reference databases to identify its probable ore deposit and retrace supply circuits.
The pigments, binders and supports of a work carry an isotopic fingerprint consistent with their era and place of production. IsoFind detects anachronistic or geographically incompatible compositions with the declared attribution.
Carbon and nitrogen isotopes in bone collagen reflect the dietary habits of an individual's last years of life. IsoFind manages palaeoecological series and compares signatures to available resource references.
Associate each piece with its isotopic data, analytical method and provenance conclusions. Records are archivable in .isof format and can be integrated into collection management systems.

IsoFind reconstructs the contamination volume by spatial interpolation, couples it to a geochemical prediction engine (physical prior + ML ONNX) and lets time scroll to show how the contaminant evolves. PFAS and pesticide tracing is available free of charge.
From your point data (wells, piezometers, soil samples), IsoFind interpolates concentrations in 3D using the IDW (Inverse Distance Weighting) method and displays the contamination volume with its colour gradient. Two visualisation modes: coloured point cloud for rapid exploration, interpolated volume for presentations. Geographic coordinates are locally normalised with cos(lat) correction to guarantee distance accuracy.
Free (PFAS / Pesticides) Pro (other molecules)The predictive engine calculates the plume's evolution over time, accounting for advective transport, adsorption onto soil minerals and degradation. A time slider allows stepping through the simulation stages, from initial state to the predictive horizon. Front velocity is calculated from hydraulic conductivity and gradient, corrected for dilution and retardation effects.
Temporal simulationThe predictive engine combines a calculable physical prior (Rayleigh, 2 end-member mixing, Cr(VI)/Cr(III) reduction, TCE/PCE/DCE degradation) and two dedicated ONNX models: an elements model (redox speciation, Kd adsorption) and an organic molecules model (reaction rate k, effective epsilon). A 936-point pH×Eh lookup table is pre-calculated at startup for fast simulation; direct ONNX call remains available for detail tooltips.
Pro licenceSlice the 3D volume at any depth with the horizontal cross-section. The Z slider allows scrolling through layers and reading predicted concentrations at each depth. Useful for delimiting risk horizons in a multi-layer aquifer or targeting sampling depths during a field campaign.
Z cross-sectionClick on any point in the 3D volume to instantly obtain the interpolated local geochemical conditions (pH, Eh, DO) and predicted speciation: Cr(VI)/Cr(III) or TCE/DCE/VC fractions depending on the molecule, local partitioning coefficient Kd, kinetic constant k_reaction, and estimated mobility. This information directly feeds risk assessment reasoning and the prioritisation of sampling points.
Pro: direct ONNXThe depth axis is often much more compressed than the horizontal axes in an aquifer. The vertical exaggeration cursor (x1 to x10) makes structures readable without distorting the interpretation. High-resolution PNG export produces an image directly usable in a report or presentation.

Visualise your data in 3D, free for PFAS and pesticides.
Download IsoFind. 3D modelling for PFAS and pesticides is included without a licence. The full predictive engine (chlorinated solvents, metals, hydrocarbons) is available in Pro.An IsoFind report is not a formatted document. It is a structured reasoning: it automatically compares multiple attribution hypotheses, argues for and against each, quantifies confidence in each conclusion, delimits what the data supports and what it does not, and seals everything cryptographically. Every assertion is factual, analytically grounded and traced back to the raw measurement.
For each attribution question (what is the probable source? is this batch compliant?), IsoFind simultaneously evaluates all candidate scenarios. Each hypothesis receives a confidence score calculated from the isotopic distance to the reference, the consistency of tracer systems and statistical robustness. The report presents the arguments for and against each scenario, the score for each, and concludes on the most probable scenario, without hiding credible alternatives.
Multi-scenario analysis Confidence score per hypothesis, argued and traceableEvery report includes a structured section explicitly listing what the data allows to conclude with confidence, what it allows to suggest with reservation, and what it cannot resolve. This rigorous delimitation of conclusions is what makes a report defensible in judicial or regulatory contexts, where an unsupported conclusion is more damaging than no conclusion at all.
Conclusion delimitationML speciation results, Nexus fractionations, concentration/time curves from the 3D simulation and attribution scores are all automatically collected and inserted into the corresponding blocks. No manual re-entry, no copy-paste: the report is a coherent projection of the entire analytical workflow.
Nexus + ML + 3DCompose your reports from reorderable thematic blocks: cover page, sample inventory, isotopic signatures, Nexus processes, ML speciation, 3D simulation, attribution scores, uncertainties, recommendations, free sections, glossary, bibliography. Three pre-configured templates cover common uses; create and save your own.
Drag-and-drop blocksEvery generated PDF is sealed by a SHA-256 hash covering all content. Any subsequent modification is immediately detectable. For judicial or regulatory use, this mechanism constitutes an enforceable integrity proof without third-party infrastructure. The audit trail records every action: generation, export, download, deletion.
