UMR SVQV analytical platform

An analysis platform to:

• identify and characterize the determinants of grape and wine quality
• search, identify and characterize defense metabolites in grapevine 
• carry out targeted or global metabolomic analyses in collaboration with national and international scientific partners

The equipment:

• two gas chromatographs coupled to mass spectrometers and equipped with automatic injector/samplers, dedicated to the analysis of volatile metabolites. One of the instruments is equipped with an olfactometric detector for characterizing grape and wine aromas. The olfactometric technique uses the human nose as a sensory detector, complementing mass spectrometry, to identify and characterize odorous molecules.
• a Thermo Vanquish UHPLC liquid chromatography chain coupled to a Thermo Exploris 120 high-resolution mass spectrometer (Orbitrap technology) for the analysis of non-volatile compounds.

The equipment for this platform was acquired with funding from INRAE (CNOC and BAP department), the University of Strasbourg, the Institut de Biologie Moléculaire des Plantes (IBMP), the Agence Nationale de la Recherche (ANR), the Comité National des Interprofessions des Vins à Appellation d'Origine (CNIV), Colmar Agglomération, the Région Grand Est and the European Union.
