摘要
This paper demonstrates the possibility of determining single gas components, such as H2, CH4 and CO, in air from specific patterns of chemically modified SnO2-based sensors. We also present results from two different multicomponent analysis approaches. In the first approach we measure conductivities of different chemically modified sensors and in the second one we measure different parameters of only one sensor. © 1990.
