The ISOTOPEST database is open to contributions.

The procedure to contribute is easy and consists in sending by email the validated isotopic data using the template table:

Molecular NameManufacturerApplied/standardIsomer ?Isomer enrichedBatch/Lot n°Commercial Name/FormulationPurity (%)δ13C (%)± (%)δ37Cl (%)± (%)δ15N (%)± (%)δ2H (%)± (%)Measurement methodReference: DOI NumberReference Citation


A brief description of the extraction and analytical methods is necessary.

Once validated, the data are included in the dataset and available in the website and free of charge.
