Abstract

A notable need for lightweight, simple-to-use portable gas analysers with facilities aimed at wide range of applications is observed in the market of measuring instruments today. In this work, a concept of portable sensing of organic vapours is presented. As the most reliable, the semiconductor gas sensor technology was chosen. However, due to high power consumption of this kind of sensors only a single sensor option is currently feasible for the portable device. In view of partial selectivity of the metal oxide based gas sensors, the unsatisfactory analytical abilities of the device could be anticipated. But, we showed that a single semiconductor gas sensor may be used for identification and quantification of the organic compounds vapours. In our solution, this goal is accomplished by applying active gas sampling. It was demonstrated that variable exposure conditions of a sensor, which are induced by the gas flow, allow for obtaining the sensor signal that has high information content. It is sufficient to characterize the test gases qualitatively and quantitatively. The achieved accuracy is very good for a screening device.
