Any atomic absorption spectrometer consists of five essential components:

• a primary light source that emits the spectrum of the element of interest;

• an atomizer, which also serves as an absorption cell, in which atoms in their ground state $({\text{E}}_0)$ are generated, and where they absorb light from the primary source;

• a monochromator, for dispersing light and selecting the wavelength to be analyzed;

• a sensor that measures light intensity...
