| 摘要 |
The invention relates to a thermal gas desorption analyzer 1 which may be integrated into a wall W of a compartment 2 confining environment E to be investigated. The analyzer 1 comprises an inner volume I adjacently arranged with the environment E. The analyzer comprising a heater 5 conceived to heat a surface which had adsorbed gas molecules from the environment E. An adsorbing surface 3a may be arranged on a cylinder, which may be rotatable about a shaft 4. In a first position 3a the surface is adsorbing gas molecules and in the second position 3b the surface, being heated by the heater 5, desorbs gas molecules, which may be carried towards a detector by a flow of a suitable carrier gas G.
