<p>EN: A Proton Transfer Reaction Mass Spectrometer (PTR-MS) was used for the analysis of syngas in an industrial Fischer-Tropsch process. A PTR-MS can detect a variety of volatile organic and inorganic compounds in real-time and with high sensitivity. Together with a multiplexer, this allows for online (real-time) monitoring of the trace contaminations at different stages of a Fischer-Tropsch process. Several volatile compounds, such as HCN, H2S, RSH, carbonyls, acids, alcohols and others have been measured in Syngas. This paper describes the setup to monitor syngas using PTR-MS and summarizes the result of this proof-of-principle project. FR: Un spectromètre de masse par réaction de transfert de protons (PTR-MS, Proton Transfer Reaction &ndash; Mass Spectrometer) a été utilisé pour l&rsquo;analyse de gaz de synthèse dans un procédé industriel Fischer-Tropsch. Un PTR-MS peut détecter une grande variété de composés organiques et inorganiques volatils en temps réel et avec une sensibilité élevée. Associé à un multiplexeur, il permet un suivi en ligne (en temps réel) des contaminants à l&rsquo;état de traces à différents stades d&rsquo;un procédé Fischer-Tropsch. Plusieurs composés volatils, tels que HCN, H2S, RSH, des carbonyles, des acides, des alcools et autres, ont été mesurés dans du gaz de synthèse. Cet article décrit la configuration pour le suivi du gaz de synthèse en utilisant le PTR-MS et résume le résultat de ce projet de preuve de concept.</p>

Die Zusammensetzung der Atemluft kann durch Erkrankungen verändert werden. Mit Hilfe von modernen analytischen Messmethoden versucht die Forschung, Zusammenhänge ­zwischen einzelnen Chemikalien und physiologischen bzw. pathologischen Vorgängen fest­zustellen. Ziel ist die nicht-invasive Frühdiagnostik von Krankheiten durch Atemgasanalysen. In einer Pilotstudie an der Innsbrucker Universitäts-Fraukenklinik wurden Atemgasproben von Brustkrebspatientinnen systematisch mit einer hochempfindlichen Methode analysiert. Eine ­signifikante ­Erniedrigung der Isopren-Konzentration der ausgeatmeten Luft vs. gesunde Kontrollen ist konsistent mit den ­Ergebnissen von Atemgasstudien bei Lungenkrebspatientinnen.

Hansel, "Breath Analysis with PTR-MS: More breath markers for lung cancer", 5th International PTR-MS Conference on Proton Transfer Reaction Mass Spectrometry and Its Applications, pp. 31-33, 2011.
In a clinical screening study we have measured several hundred subjects using real-time breath analysis with PTR-MS. We present and discuss potential breath markers for lung cancer with a critical view on the data analysis. The presented problems and solutions are also applicable to other analytical methods used in breath analysis.

We present a method for measuring liquid samples with the PTR-MS by using a spray to convert the liquid into the gas phase. Advantages over headspace measurements concerning compounds with high Henry's law constants could be demonstrated.
