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. Capture the stories hidden in your samples with the Thermo Scientific portfolio of isotope ratio mass spectrometers. 

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.
