Significant loss of meronry can be prevented in the eleotrothermal atomizer during desolvation and oharring stages when miorogram amounts of noble metals snoh as gold,platinum and palladium are used as stabilizers to modify the matrix.A charring temperature up to 500℃ may be tolerated in the presence of palladium,whioh is 200℃ higher than that obtained with the use of sulfide reported in the literature.Thehigher oharring temperature is a distinot advantage for eleotrothermal atomic absorptien spectrometry since organic compounds can be easily burnt off,and hence molecular absorption eliminated.
