Analysis
Stable isotopes
Stable isotopes carry valuable informations to answer a variety of questions.
The following analyses in the area of stable isotopes are part of our portfolio:
| Isotope | Medium | Method |
| 18O/16O | water (H2O), SO4, NO3, juices, alcoholic drinks, eggs, rock (gypsum), soil (NO3) | IRMS, CRDS |
| 2H/1H | water (H2O), CH4, higher hydrocarbons (C1-C4), H2, CHC, BTEX, food additives | IRMS, GC-MS-IRMS, CDRS |
| 13C/12C | water (DIC, DOC), CH4, C1-C4, CO2, CHC, BTEX, food, food additives, organic compounds | IRMS, GC-MS-IRMS |
