The charring and atomization temperatures and times and the amount of modifier were optimized. The calibration and addition graphs, detection limit, quantitation limit precision, accuracy, interferences, and characteristic mass were also investigated. The method was applied to the determination of ...

Here the reversible deposition and dissolving of atomic Sn on the Cu electrode was directly confirmed by the EQCM characterization. As shown, the mass on the electrode presented a clear and sharp increase as a result of the Sn deposition and then gradually decreased to the original value because...

The addition of copper nitrate served to eliminate the interferences from 104–105-fold concentrations of foreign elements at the 890 °C pyrolysis temperature. The absolute characteristic mass (giving 0.0044 absorbance) of gold in the presence of copper nitrate with the Mo atomizer was 0.26 pg ...
