Using environmental tracers to prove product authenticity and origin
Using naturally occurring isotopes, elemental analyses and biological remnants as environmental tracers, researchers at GNS Science are developing analytical verification methods and supporting datasets to prove product authenticity and origin, support consumer confidence and aid in the sourcing of items.
