A continuous flow mass spectrometer Delta V Plus (Thermo Fisher Scientific) linked by an interface ConFlo IV to an elementary analyser Flash EA IsoLink CN, option SmartEA, and a gas chromatograph GC 1310-Isolink II, equipped with an automatic sample changer Triplus RSH.
These systems can be used to measure δ13C and the δ15N of powders and measurements of δD and the δ13C of organic molecules separated by gas chromatography.

The compositions in δ13C and δ15N of powders and δD and δ13C of organic molecules are analysed at CEREGE for :
- Tracing vegetation changes (δ13C on n-alkanes)
- Tracing changes in the carbon cycle (δ13C on alkenones)
- Reconstruction of past changes in the hydrological cycle in the continental domain (δD on n-alkanes, triterpenes, etc.)
- Reconstruction of past hydrological cycle changes in the marine domain (δD on n-alkenones, sterols, etc.)
- Measuring soil organic carbon turnover to feed carbon cycle models
- Characterisation of organic matter stabilisation processes in soils
- Characterising the impact of climate change on biodiversity and the biodegradation of forest litter
