Abstract
Metal oxide gas sensors alter the gas composition during the sensing process. This peculiarity can be used as an advantage to obtain additional information in order to identify the analyte gas or to determine the composition of a gas sample. For that purpose the former sensors can be seen as catalytic filters which increase selectivity in a sensor array or even produce it if the array consists of identical sensors. In this work the described concept was proven and first steps were done to understand the influence of several variables on this effect in order to fully exploit the increase of selectivity.
