Actually, the rapid detection of explosive agents in air has become a real need. In this context, the aim of this research work is to develop a micro-fluidic platform integrated on a silicon substrate for the monitoring of explosive traces in air. This platform is composed by a micro-preconcentrator followed by a chromatographic micro-column and a tin oxide- based sensor. The target molecule studied is the orthonitrotoluene (ONT) known as a simili vapor of trinitrotoluene...
