This paper presents the optimization of a micro gas preconcentrator applied to environmental monitoring. Different types of adsorbent materials introduced in silicon microchannels with various designs have been investigated and a special focus has been dedicated to the modes of operation of the preconcentrator. The optimization of the device and its operation were driven by its future application...
This paper presents the development of a gas pre-concentrator based on a micro-reactor in porous silicon filled with carbon nanopowders in solution. The particularity of this microsystem is its applicability in the fields of atmospheric pollution monitoring and explosives detection. The performances of the device are closely related to the design of the micro-reactor and the choice of the adsorbent...
