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 WebAtomic Absorption Spectroscopy is an instrumental analysis technique for rapid trace metal analysis.It is based on element specific wavelength light absorption by ground state …
