Abstract
Un chromatographe gazeux portatif comprend un ruban (220) d'adsorption d'échantillon ayant une position (205) d'échantillonnage et une deuxième position (206) de désorption. L'échantillon est désorbé par l'activation de dispositifs de chauffe (210,211). L'échantillon désorbé traverse ensuite une colonne chromatographique (209b) qui est chauffée par un troisième dispositif de chauffe (212). L'échantillon séparé est ensuite envoyé à un détecteur (213) qui effectue l'analyse.
