Abstract: A sampling cartridge (1), a sampling device (2, 3), an extracting device (4) and a sampling and extracting device (5) which allow safe measurement without contamination of the adsorbent, before or after sampling. The sampling cartridge (1) comprises an envelope (10) made from an inert material in which an adsorbent material (13) is sealed, in a leaktight manner, by two caps (11, 12) located at the two ends (100, 101) of the envelope. Each cap (11, 12) has an opening (111, 121) which is closed by a seal (110, 120) formed of a silicone film and a barrier layer made of aluminum which withstands the high temperatures necessary for the thermal desorption technique. The cartridge (1) is conditioned under inert gas and its ends (100, 101) comprise at least one seal-on end piece (102) for a cap, and one universal end piece (105) for a sealed, screwed or clip-fastened cap.
