A method of capturing volatile components whereby volatile components contained in a solid substance such as tobacco leaves can be surely captured. An apparatus provided with a sample tube (10) in which a sample comprising a solid substance containing volatile components is contained, a gas-filling unit (16) by which an inert gas is filled into the sample tube, a thermostat (12) in which the sample tube is packed and the sample contained in the sample tube is maintained at a definite temperature, and a canister (20) which is selectively connected to the sample tube under preliminarily reduced pressure. After filling the sample tube contained a sample (S) therein with an inert gas, the sample is maintained at a definite temperature. Next, the canister under preliminarily reduced pressure is connected to the sample tube and the components vaporized from the sample are thus captured.

L'invention concerne un procédé de capture de composants volatils tels que ceux contenus dans une substance solide comme des feuilles de tabac. L'appareil comprend un tube échantillon (10) dans lequel est introduit un échantillon solide contenant des substances volatiles, une unité d'alimentation en gaz (16) au moyen de laquelle on peut introduire un gaz inerte dans le tube échantillon, un thermostat (12) dans lequel est enfermé le tube échantillon permettant de maintenir l'échantillon du tube à une température constante, et un absorbeur (20) relié sélectivement au tube échantillon après avoir été mis sous pression réduite. Après remplissage du tube contenant l'échantillon (S) par du gaz inerte, l'échantillon est maintenu à une température définie. Puis l'absorbeur sous pression réduite est mis en connexion avec le tube échantillon et les composants volatiles provenant de l'échantillon sont alors capturés.
