Other Analytical Services for 13C, 15N, 18O, and 2H

We also offer stable isotope analysis for environmental water monitoring. Water in different environments develops isotopic “fingerprints” (abundance of deuterium and oxygen-18) that can be traced. The movement of surface and ground water can also be investigated by artificial tracing. Isotopic water can be purposely injected into the water and detected at some other point in the system.

Food adulteration and authentication is another stable isotope analysis service we offer. The carbon-13 isotopic fingerprint of authentic material can reveal adulteration and/or authentication of food ingredients.
