Introduction

Welcome to the official IsoFind documentation. This software is designed to centralise and exploit your isotopic data while guaranteeing their integrity through the ISOF standard and its cryptographic signature.

IsoFind was designed as a bridge between scientific complexity and operational efficiency. Its interface guides field users through step-by-step assistance modules, while advanced users retain full control over calculation parameters, fractionation algorithms and metadata export.

Guided mode

Ideal for technicians and field agents. Automated workflows for ISOF certification without a steep learning curve.

Expert mode

Full access to parameters, customisation of fractionation databases and advanced management of cryptographic signatures.

IsoFind operates entirely locally. No data transits through the cloud, ensuring compliance with the most stringent security requirements, including in air-gap mode.

Dashboard and Visualisation

The dashboard centralises the intelligence of your data. More than a simple sample list, it integrates IsoFind's analysis engine, which continuously evaluates the quality of your measurements: outlier identification, statistical robustness verification, per-sample reliability score. Data is therefore always ready for analytical, forensic or industrial use.

The ISOF Standard

The ISOF format (Isotopic Open Format) does not merely store isotopic ratios. It encapsulates the complete analytical lineage: digestion protocols, purification yields and reference standards. The ECDSA P-256 signature makes this capsule tamper-proof, guaranteeing full traceability and admissibility during inter-laboratory exchanges.

Documentation Structure

The documentation is organised into five sections accessible from the sidebar:

Section	Contents
