Detection of Dynamic Smell Intensity

Characterisation Of Explosives By The Response Of Gas Sensor Array To Modulated Intensity Of The Smell

  • Conference paper
Book cover Electronic Noses & Sensors for the Detection of Explosives

Part of the book series: NATO Science Series II: Mathematics, Physics and Chemistry ((NAII,volume 159))

Abstract

A method increasing the rate of the detection of complex volatile compounds by solid-state gas sensors is proposed. An original approach includes special modulation of the smell intensity and analysis of the kinetics of the sensor response. Essential aspects of the method are theoretically described considering dynamics of the processes in the model of the response of solid-state sensors to gas. The experimental transients of the response of metal oxide thin film sensors to a step change in gas composition of the atmosphere are analysed considering controlled injection of volatile compounds of pure TNT and explosive mixtures containing TNT.
