IsoFind Essential, the isotopist's workspace, free for life

IsoFind Essential Free for life

Enter, visualize, archive. All your isotopy in one place.

The isotopist's workspace, built for research and teaching. A structured database for your samples, CRMs and standards, a spreadsheet wired to that database with its geochemical formulas, the mapping of your sites, figures ready for publication and durable archiving in the open ISOF format. No subscription, no limits, no compromise on your data.

The daily reality of isotopic data

Your data deserves better than a spreadsheet.

Isotopic results too often end up scattered across spreadsheets, notebooks and figure folders. The CRMs and calibration standards are recorded nowhere reusable, graphs are rebuilt by hand for every paper, and nothing guarantees that a file opened five years from now will still be readable and intact.

i.

Scattered data

One sheet per measurement session, naming conventions that drift, columns that no longer line up. Finding a value six months later becomes an investigation.
ii.

Undocumented calibration

Which CRM, which standard, which uncertainty for this batch? That information rarely sits next to the data, which undermines reproducibility and review.
iii.

Figures rebuilt endlessly

Every isotopic diagram is reconstructed by hand for each manuscript, with the transcription errors that invites.
iv.

No durability guarantee

A proprietary format or a plain spreadsheet says nothing about file integrity. A cell changed by mistake goes unnoticed.

What Essential does

One tool, from measurement to publication.

Essential brings together in a standalone application everything a research lab needs day to day: a database, a spreadsheet wired to that database, its geochemical formulas, the mapping of its sites and its publication figures. The scope covers isotopic, elemental and molecular geochemistry, it is fixed and identical to the paid editions for everything related to data entry.

Storage

A database built for isotopy

Enter and structure your samples with the same depth as the professional editions. Isotopic, elemental and molecular geochemistry supported, with no volume limit.

Full management of samples and projects
Isotopic, elemental and molecular geochemistry
Analytical metadata (site, matrix, method, uncertainty)
Backup and restore of your databases

Spreadsheet

A spreadsheet wired straight to your database

Not a separate file: a spreadsheet connected to the database, where your geochemical formulas recompute the moment the data changes. Extensible through plugins.

Tabular editing wired to the database, no export-import
Built-in geochemical formulas (York regression, delta calculations)
Extensible through plugins for your own processing

Reference materials

CRMs, standards and automatic standardization

Your certified reference materials and standards live next to the measurements they calibrate, and standardization is applied automatically to your batches.

Reusable library of CRMs and standards
Automatic standardization of batches against their references
Delta conventions and scales (VPDB, VSMOW, and others)

Visualization

Figure templates ready for publication

Build your diagrams straight from the database, with no re-entry, from templates designed for manuscripts, and export them in high resolution.

Publication-ready graph templates
Isotopic and elemental diagrams and scatter plots
High-resolution export, automatic updates

Mapping

Your samples on the map

Place your sampling sites back in space and read the geographic distribution of your values straight from your database.

Sampling-site location
Spatial reading of isotopic and elemental values
Map view wired to the database

Archiving

The open ISOF format, intact and durable

Keep and share your datasets in an open, verifiable and durable format. An ISOF file stays readable and its integrity remains checkable, without depending on IsoFind.

Reading and production of ISOF files
Tamper detection on opening
Verifiable for free by the whole community

Why not just a spreadsheet

The difference shows from the first dataset.

A spreadsheet can line up numbers. It knows nothing about your standards, your delta conventions or the integrity of your files. Essential is built around the isotopic object itself.

Genuinely free

Not a trial. A complete product, for life.

Essential is a standalone application, compiled separately, with its own scope. It is not an evaluation version that locks after thirty days, nor a demo dotted with greyed-out modules. What you install today stays free and complete.

No license

No key to buy, no account to create, no renewal. You download, you install, you work.

No limits

No sample ceiling, no watermark on exports, no hidden throttling of the Essential scope.

No collection

No telemetry, no usage tracking, no advertising. Your data stays on your machine, full stop.

Air-gap compatible

Fully functional with no internet connection, suited to isolated machines and sensitive environments.

Windows application

Native Windows application. Linux and macOS versions are coming, not available yet.

Durable format

The ISOF format is open and independent of the commercial range. Your archives depend on no vendor.

No trackers, no advertising, no hidden subscription.

Your data stays yours

Sovereign by design.

Research handles sensitive data before publication. Essential was built so that it never leaves your machine without your explicit decision.

100% local storage

No copy is sent to a server, no dependency on an online service to open or edit your datasets.

Cryptographic integrity

The ECDSA signature of an ISOF file detects any tampering on opening. Altered data no longer goes unnoticed.

No lock-in

The format is open and documented, published under the MIT license. Any system can read and verify an ISOF file, even without IsoFind.

And the day your lab grows

Essential offers the same data entry depth as the professional editions. The day you need advanced geochemical analysis, 3D simulation or certifiable reports, you move to IsoFind Pro without re-entering or converting your data. Your samples, your CRMs and your standards come with you.
