Scientific correspondent : Claude Le Milbeau
Brand and model :
CDS Pyroprobe 5150 Pyrolyzer coupled to a Thermo Scientific Trace 1310 gas chromatograph (GC) and a Thermo Scientific ISQ7000 mass spectrometer (MS)
Principle :
Pyrolysis of soils/sediments/vegetation, separation of pyrolysates by GC, identification and quantification by mass spectrometry
Objectives :
Characterization of insoluble organic matter by flash pyrolysis or by temperature ramp.
Samples treated :
Soils, sediments, plants, rocks, peat.
Pre-treatment :
Drying and grinding of the sample. Pyrolysis assisted by TMAH.
Results :
Chromatograms, mass spectra, abundance of phenols from lignins, acids, sugars.
