Conteúdo: | Analyses of mercury traces on 32 different samples mostly food (cereals, milk, fish, havebeen carried out. To this purpose the AMA-254 mercury analyzer has been employed. This unit doesn't require any sample digestion; therefore the instrumental reading takes place on the sample as is, either solid or liquid, thanks to atomic spectroohotometry at the wavelenght of 253.65 nm. Usual global working range is estimated in 0-2 mg/kg with particular relevance in the interval 0-0.2 mg/kg. Accuracy is evaluated in acordance with reference standards at known concentrations. Precision is assessed thanks to repeatable tests on hormogeneous and heterogeneous samples. The limit of experimental measurement is calculated to be 0.5 ug/kg.
