Abstract: Bekannte Verfahren und Einrichtungen sind für solche Gasverbindungen ungeeignet, die einen hohen Anteil von höherkonzentrierten und für die Selektion ungeeigneten Bestandteilen aufweisen, wie beispielsweise Ethanol in alkoholischen Getränken. Meßergebnisse an diesen Gasverbindungen sind verfälscht. DOLLAR A Ein weiterer Nachteil besteht darin, daß die Gassensoren keine lineare Konzentrationskennlinie erzeugen. Das führt zu unterschiedlichen Mustern. DOLLAR A Es wird daher ein neues Verfahren und eine entsprechende Einrichtung vorgeschlagen, das die Gasproben durch eine Verdünnung mit einem gefilterten Luftstrom auf einen konstanten Konzentrationswert regelt und das die Gasproben im Bedarfsfalle durch Adsorbtion und anschließender thermischen Desorption von leichtflüchtigen Gasanteilen trennt und befreit.
