Abstract:
1. An analyte detector for detecting an analyte, comprising: a housing defining an enclosed sensing volume adapted to pass a carrier and having an adsorption/desorption zone, the housing having an inlet and an outlet communicating with the enclosed sensing volume such that a carrier gas can be moved sequentially through the inlet, the enclosed sensing volume and the outlet; means for effecting selective adsorption/desorption of at least a portion of the molecules of the analyte in the adsorption/desorption zone of the housing; a sensing assembly for sensing the analyte delivered by the carrier, the sensing assembly being downstream from the adsorption/desorption zone whereby the carrier passes through the adsorption/desorption zone prior to delivering the analyte to the sensing assembly, the sensing assembly comprising:
