Hydrogen and oxygen stable isotope measurements on roasted coffee samples trace the origin of coffee beans based on unique trends observed from their isotopic fingerprints.

The measurement of carbon, nitrogen and sulfur isotope fingerprints of PM2.5 particles on quartz filter papers allows source identification.

With isotope fingerprints sources of pollution, monitor water and air quality and track environmental change across space and time can be traced. Isotope Ratio Mass Spectrometry detects the “isotope fingerprint” of a sample, a unique chemical signature that changes from sample to sample across the environment.

Hydrogen and oxygen stable isotope measurements on roasted coffee samples trace the origin of coffee beans based on unique trends observed from their isotopic fingerprints.

Synthetic copies of endogenous steroids are chemically and pharmacologically identical to their endogenous analogs. Analyzing isotopes of the steroids provide characteristic isotope fingerprints of urinary steroids and offer a discrimination framework.

Analysis of cocaine seized from an “aircraft drop” in Uruguay led to the discovery of a previously unknown coca growing region in northern Bolivia.
