In this work we present the use of EMFAAS (Electrothermal Metallic Furnace Atomic Absorption Spectroscopy) for the determination of Cd in tobacco cigarettes of five commercial brands. Optimization of the experimental conditions was done by controling the sample flow rate and the temperature of both, the injection capillar and the atomization cell . The determination was made in the whole cigarette and in filters and ashes of the cigarettes once consumed, cases in whichthe Cd concentration is much lower and its quantification more difficult. For the validation of the results, the ICP-OES technique was used, obtaining a good agreement within the experimental error. The results show that EMFAAS is a promissory tool for the determination of volatile analytes.
