heal.abstract	Long term performance of tin and indium oxide thin films with palladium and platinum deposited on their surface as catalysts was studied using a standardization method proposed recently by other researchers. A simple gas classification algorithm was used to investigate the validity of the standardization method proposed and to study the effect of doping type and thickness onto the surface of SnOx and InOx films on their selectivity and stability characteristics. It was found that: (a) the proposed method is reliable for the assessment of sensor degradation; and (b) sensors with relatively thick additive layer are more reliable.
