Tools
- Picarro G2201 optical cavity resonance gas analyser (CRDS)-i for determining δ13C in the CO2 and the CH4
- Combustion module for the preparation of solid samples
- Multiplexer recirculation module (16 x 2-port) for continuous-flow analysis
- Sampler automated gas system (SAGE) for the analysis of discrete gas samples

Applications
Measuring the concentrations of CO₂ emitted by the soil and its isotopic composition (¹³C/¹²C) makes it possible to:
- Accurate quantification of soil respiration, to monitor the rates of mineralisation of organic matter (OM) stabilised in nanoCLICs and to understand the processes and dynamics of carbon in soils.
- Real-time isotopic tracing to detect the fluxes of labelled CO₂ released by microbes and to quantify the dynamic carbon exchanges between nanoCLICs, rhizodeposition and microorganisms.
The equipment is financed by and used exclusively for the project's research. ERC (ADG) NANOCLICS, awarded to Isabelle Basile-Doelsch (2026–2030)
