Isotope Fingerprinting

Investigating authenticity and tracing origin using isotopic fingerprinting

Investigators can track origins, authenticity and trace identity using the isotopic fingerprints (isotopic signatures) that are left behind in food, fiber, liquid or stone. Isotope mass spectrometry (IRMS) can help identify the isotopic signatures that provide information about a geographic region, botanical processes, soil or fertilization processes.

Isotopic fingerprints help uncover the history of your samples

Samples have unique chemical signatures, or fingerprints, that provide clues to their histories. Isotope ratio mass spectrometry (IRMS) can help visualize these fingerprints. IRMS traces carbon, nitrogen, sulfur, oxygen, and hydrogen isotopes by detecting their natural variations, revealing the origin and history of samples.
