Abstract

La présente invention concerne un procédé d’analyse sensorielle d’échantillons de gaz industriels livrés sur un site industriel consommateur, se caractérisant par la mise en œuvre des mesures suivantes : - on dispose d’une enceinte hermétique dans laquelle est placé un système de détection, qui comporte l’un ou chacun des systèmes de capteurs suivants: i) une ou des cellules électrochimiques; j) un ou des capteurs de type MOS (« Metallic Oxides Semiconductor ») ; - on introduit dans l’enceinte l’échantillon de gaz ; - les cellules et/ou capteurs présents dans l’enceinte vont réagir en présence de composés organiques éventuellement présents dans l’échantillon de gaz, et fournir une réponse de détection ; - on dispose d’une système d’acquisition et de traitement de données ; - on a réalisé au préalable, une phase d’apprentissage de l’analyse par un panel humain, et on réalise, à l’aide dudit système d’acquisition et de traitement de données une opération de réconciliation des deux types de données, i.e. les résultats des tests réalisés par le panel humain et les résultats fournis par les capteurs et/ou cellules dans l’enceinte.The present invention relates to a process for the sensory analysis of industrial gas samples delivered to an industrial consumer site, characterized by the implementation of the following measures: - there is a hermetic enclosure in which is placed a detection system , which includes one or each of the following sensor systems: i) one or more electrochemical cells; j) one or more MOS (Metallic Oxides Semiconductor) type sensors; - the gas sample is introduced into the enclosure; - the cells and/or sensors present in the enclosure will react in the presence of organic compounds possibly present in the gas sample, and provide a detection response; - a data acquisition and processing system is available; - we carried out beforehand, a learning phase of the analysis by a human panel, and we carry out, using said data acquisition and processing system, a reconciliation operation of the two types of data, i.e. the results of the tests carried out by the human panel and the results provided by the sensors and/or cells in the enclosure.
