In order to overcome problems due to the conventional sensors detection limits, a preconcentration system is required. Accumulation of vapor(s) for detection is possible with an adsorbent and allows releasing them toward a detector, under the effect of a sudden rise of the temperature. Amplification of the concentration and the signal are obtained.This thesis continues the development of a preconcentrator for the detection of toxic gas and explosives. This preconcentrator is made of a silicon microcomponent filled with an adsorbent and a heater at its back. Two metal capillary allow ensuring the gas flow into the device. Various designs of preconcentrators were developed with different adsorbents to satisfy the requirements for volatile or...
