ABSTRACT:
A diffusion sampler includes a vessel which has at least one inlet opening exposed to the gas to be investigated and which has a moderating zone. In its interior, the vessel has a collecting region provided with a collecting medium as well as a conversion region for converting the gas into substances which can be taken up by the collecting medium. The diffusion sample is improved in that its detection sensitivity is increased and that the collecting region as well as the converting region are provided with large areas in a manner adapted to the geometry of the vessel so that a smaller and more manipulable configuration is obtained. In addition, long-term dosimetry is made possible. For this purpose, the moderating zone is configured as a permeable barrier from which the converting region as well as the collecting region extend and determine the diffusion path in the entire interior of the vessel with each region being applied to a carrier.
