Abstract

L'invention concerne un dispositif de mesure comprenant un appareil de mesure pour échantillons en particulier gazeux et un dispositif d'introduction d'échantillons au moyen duquel les échantillons sont amenés à l'appareil de mesure. Pour améliorer un tel dispositif de façon que les résultats de mesure et/ou d'analyse de l'appareil de mesure ne subissent pas l'influence d'éventuelles contaminations, il est proposé que le dispositif d'introduction d'échantillons soit pourvu d'un dispositif de nettoyage servant à nettoyer les zones de contamination de ce dispositif d'introduction d'échantillons, ce nettoyage consistant à transformer les impuretés se trouvant dans les zones de contamination par réaction chimique, et que les produits de réaction formés soient évacués du dispositif d'introduction d'échantillons.
