Basic Principles of Atomic Absorption and Atomic Emission ...

44 • Flame Emission -> it measures the radiation emitted by the excited atoms that is related to concentration. • Atomic Absorption -> it measures the radiation absorbed by the unexcited atoms that are determined. •Atomic absorption depends only upon the number of unexcited atoms, the absorption intensity is not directly affected by the

Atomic absorption measurements were carried out using a Varian AA240 spectrometer with a Mg/Ca hollow cathode lamp light source (7 mA lamp current ). Atomization was performed using an air/acetylene flame. The instrument was zeroed with 2% HNO 3 and rinsed between each collection with deionized water. Magnesium

Atomic Absorption Spectrometry (AAS) - IntechOpen

The instrument used for atomic absorption spectrometry can have either of two atomizers. One attachment is a flame burner, which uses acetylene and air fuels. The second attachment consists of a graphite furnace that is used for trace metal analysis. Figure 1 depicts a diagram of an atom ic absorption spectrometer. Fig. 1.
