Atomic Absorption Spectroscopy 4 Spectroscopy (ICP-OES), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), have left Atomic Absorption (AA) behind. This technique, however, is excellent and has a larger specificity that ICP does not have. Figure 2 shows a diagram of an atomic absorption spectrometer with a graphite furnace. Fig. 2.

What is Atomic Absorption Spectroscopy (AAS) Atomic absorption spectroscopy, or AAS, is a technique for measuring the concentrations of metallic elements in different materials. As an analytical technique, it uses electromagnetic wavelengths, coming from a light source. Distinct elements will absorb these wavelengths differently.

Atomic Absorption Spectrometer. Atomic absorption spectroscopy (AAS) is used to analyze metal samples by determining the presence and concentration of metals in a liquid sample. Metals include Fe, Cu, Al, Pb, Ca, Zn, Cd and many more. It also measures the concentrations of metals in the samples. Typical concentrations range in the low mg/L range.

This practice is known as atomic absorption spectroscopy (AAS). AAS was first deployed back in 1859 by Gustav Kirschoff and Robert Bunsen to detect the presence of certain atoms in flames and gases. Since then, the modern approach to AAS has been revolutionised, most noticeably by A. C. Walsh and C. T. J. Alkemade in the 1950s.
