To increase CO sensitivity, SnO2 sensors are doped with a palladium compound. A procedure has been developed to determine quantitatively the ratio Pd/SnO2. It is possible to derive the amount of impregnated Pd in the samples using ICP-MS with a precision of approximately 5%. (C) 2000 Elsevier Science S.A. All rights reserved.
