Abstract
Elément support d'échantillon pour spectromètre de masse pour la détermination quantitative de substances. La détermination quantitative de substances par la spectrométrie de masse qu'il a été jusqu'ici très difficile d'effectuer est rendue possible par l'utilisation de l'élément support d'échantillon de présente invention. Cet élément est constitué d'un agrégat de substances d'ossature poreux et perméable au gaz ayant des propriétés réfractaires et d'isolation électrique,apportant une remarquable amélioration de la sensibilité et de la précision. La détermination des composants d'un mélange échantillon est également permise sans aucune étape de séparation préalable. Application aux spectromètres de masse.
