Standard methods for the examination of water and wastewater (543.3 APHA 24th ed. Ref. Treatises&monographs FL2)
Electrothermal atomic absorption permits determination of most metallic elements with sensitivities and detection levels from 20 to 1000 times better than those of conventional flame techniques without extraction or sample concentration. This increase in sensitivity results from an increase in atom density within the furnace as compared to flame atomic absorption. Many elements can be determined at concentrations of, or below, 1.0 μg/L. An additional advantage of electrothermal atomic absorption is that only a very small volume of sample is required...
