Introduction Atomic Absorption Spectrometer (AAS) is an analytical equipment commonly used for the detection of heavy metals in particular sample. The first step to analysis in the AAS is the atomization of the desired element by converting it to a gaseous state. The atoms then absorb the energy emitted from the hollow cathode lamp corresponding to the desired element and a detector reads the signal and records the results.
