摘要
This work shows that laser excited atomic fluorescence spectrometry, LEAFS, combined with electrothermal atomization, ETA, is useful for the determination of trace concentrations of mercury in small amounts of silver metal. Only minimal sample preparation procedures, such as dilution of very concentrated solutions and digestion of solid samples, are necessary. The practical limit of detection for this work is found to be blank limited, 50 pg/ml, and the instrumental limit of detection was laser scatter limited at 7 pg/ml.
