Abstract (en)
[origin: WO9940422A1] 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.
