CA 2320445

A portable gas chromatograph includes a sample adsorbing ribbon (220) having a sampling position (205) and second desorbing position (206). The sample is desorbed by activating heaters (210, 211). The desorbed sample passes to a chromatography column (209b) which is then heated by a third heater (212). The separated sample is passed to a detector (213) for analysis.

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.
