Développement d'un analyseur de gaz transportable : couplage thermodésorbeur / micro-chromatographe / spectromètre de masse (m-TD / m-CG / SM)

Abstract : Volatile organic compounds (VOC) play a central part in the photochemical pollution of the atmosphere. Monitoring of these products in air became a need, because of their toxicity. Currently, traditional analytical methods of air have drawbacks. Instruments are too specific or the technique consists in trapping pollutants and then to turn over the sample to the laboratory for analysis. The subject of the thesis is the development of an on-site analytical technique, offering new prospects for air analysis. The developed transportable analyzer results from the coupling of a thermal desorber (m-TD), a micro gas chromatograph (m-GC) and a mass spectrometer (MS). The instrument makes it possible, in a few minutes, to perform qualitative and quantitative analysis of a very broad range of VOC at traces level. An example of on-site application of the analyzer relates to the monitoring of working atmospheres.
