In order to analyze a sample for its atomic constituents, it has to be atomized. The atomizers most commonly used nowadays are flames and electrothermal (graphite tube) atomizers. The atoms should then be irradiated by optical radiation, and the radiation source could be an element-specific line radiation source or a continuum radiation source. The radiation then passes through a WebSep 16, 2024 · Atomic absorption spectroscopy is a precise a nalytical technique. It is used for the quantification of metals present in the analyte. It is one of the best techniques to detect the sample at trace levels such as part per billion (ppb). Atomic absorption spectroscopy was developed by Alan Walsh in the 1950s.
