Despite the rise of newer technologies like ICP-OES or ICP-MS, Atomic Absorption Spectrometry remains a staple in labs for several reasons:
Compared to mass spectrometry, AAS has lower operating costs and requires less expensive consumables. atomic absorption spectrometry
A detector measures the light that made it through the sample. By comparing the initial light intensity to the final intensity, the system calculates the absorptance , which translates directly to the concentration of the metal.
