A sampling and analysis

The present invention relates to both a cartridge (1), a sampling device (2, 3) and an extraction device (4) which allow a reliable measurement without contaminating the absorbent before or after collection . And the cartridge (1) for removing according to the invention comprises a cylindrical housing (10) in an inert material in which is disposed an absorbent material (13) and sealed by two caps (11, 12) at both ends ( 100, 101) of the cylindrical casing (10), it is characterized in that each cap (11, 12) has an opening (111, 121) which is closed by a seal (110, 120) made of a film silicone and an aluminum barrier layer. The use of a specific silicone film and aluminum or aluminum / silicon / aluminum can withstand the high temperatures required for thermal desorption technique is between 250 ° C and 350 ° C.
