CA 2320800

A portable gas chromatograph-ion mobility spectrometer (GC-IMS) includes a sample adsorbing ribbon (220) having a sampling position (205) and second desorption 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 cold ion mobility spectrometer (213) for analysis.

L'invention concerne un spectromètre portable de chromatographie en phase gazeuse-mobilité ionique (GC-IMS), comprenant un ruban (220) d'adsorption d'échantillon présentant une position d'échantillonnage (205), et une seconde position de désorption (206), l'activation de dispositifs de chauffe (210, 211) permettant la désorption dudit échantillon. Une fois désorbé, cet échantillon traverse une colonne de chromatographie (209b), qui est ensuite chauffée par un troisième dispositif de chauffe (212), l'échantillon séparé traversant ensuite un spectromètre de mobilité ionique froid (213), afin d'être analysé.
