Abstract

This paper presents a cost effective electronic nose prototype for the detection of 1.6 ppm of dimethyl methylphos-phonate (DMMP) in a complex background. The device comprises seven cross-sensitive functionalized carbon nanotube (F-CNT) based sensors, an impedance measurement circuit and a micro-computer for data pre-treatment and classification stages. This study focused on the detection of DMMP in a gas mixture, using the responses of the sensors before they reach a stable and repeatable behavior. Even with this major constraint, the support vector machine used for classification reached 98 % precision for the recognition of the samples.
