EA/GA-IRMS (Elementar, Isoprime, Thermo)

Elemental analysers (EA) are connected to isotope ratio mass spectrometer (IRMS) and dedicated to δ¹³C and δ¹⁵N analyses, together with total  C and N concentration, on plant materials, soils and gas samples, either at natural abundance or after isotope labelling (enriched samples).

Pyr/EAHT-IRMS (Eurovector, Elementar, Isoprime)

A pyrolyser and a high temperature elemental analyser are connected to an isotope ratio mass spectrometer (IRMS) and dedicated to δ¹⁸O and δD analyses on organic matter and water samples, either at natural abundance or after isotope labelling.

LC/GC-IRMS (Dionex, Agilent, Isoprime)

A liquid chromatrography (LC) or a gas chromatography (GC)  are connected to an isotope ratio mass spectrometer (IRMS) and dedicated to specific compound isotope analysis (δ¹³C and δ¹⁵N in sugars, amino acids …) in liquid samples, either at natural abundance or after isotope labelling (enriched samples).

TGA100A (Campbell Scientific)

The Trace Gas Analyser is dedicated to the measurement of the concentrations of CO2 isotopologues in an air flux using tunable-diode laser absorption spectroscopy (TDLAS).

Cryoextraction line

Cryogenic distilation under vacuum for extracting water from plant and soil samples prior isotope analysis.

Microbalances

Four microbalances are available for weighting very small amounts of ground plant or soil samples prior isotope analyses.
