The limit of detection (LOD), defined as the concentration corresponding to 3-fold the standard deviation of the method blank divided by the slope of the analytical curve, was determined by analyzing ten replicates of the method blank. For the method blank, the smoke collec- tion process was applied without actually burning the cigarette. The method blank represents all aspects of the smoke collection process and sample preparation. The LODs for Cd using TS-FF-AAS and GFAAS, were 5.8 and 1.5 ng/cigarette, respectively, for the analysis of smoke condensate from 1 cigarette.
