Zusammenfassung:	Device to implement the method according to claim 1, wherein it is constituted of a vessel (2) provided with an intake tube (4) and an evacuation tube (8) for the gaseous atmosphere and whose inside forms the closed sampling space, is subdivided into a large number of small elementary intercommunicating volumes so as to enable the taken gaseous sample to be homogenized, as well as to allow for the diffusion and the spatially homogeneous trapping of all the solid daughter products thus constituing a homogeneous emitting source for the spectrometry chain which examines this source from outside.
