The sensitivity and selectivity of SnO2-based elements to ethanol vapour (1000 ppm) in air at 300 °C are found to be markedly promoted by the addition of several basic oxides, among which La203 is the most influential. The promoting effect seems to appear through a change of the reaction selectivity
Being unselective, SnO,-based gas sensors can be used by means of appropriate methods. Various techniques, e.g., pattern recognition or time modulation of the sensor temperature are used. The lack of selectivity is compensated also when one uses these sensors in chromatographic systems. The chromato
