Summary :
CGéant aims to acquire a gas chromatography with flame ionization detector for reliable separation and quantification of molecular biomarkers derived from various natural and anthropic matrices. In addition, an H2 generator will serve as vector gas for all our GCs and will feed the detector of the new instrument or an N2 generator that serves to remove the organic solvent used during the extraction of analytes. This equipment will complement the molecular biomarker analysis capabilities at LSCE integrated into the PANOPLY platform and the RéGEF community. With this instrument, it will be possible to identify and quantify the organic compounds preserved in a large number of archaeological, paleoenvironmental and environmental samples and select those of interest for analysis by gas chromatography-mass spectrometry (GCMS) and GC- Isotope ration mass spectrometry (IRMS), as well as for compound-specific radiocarbon analyses.
