The technique makes use of absorption spectrometry to assess the concentration of an analyte in a sample.

Briefly, the technique is based on the fact that free atoms will absorb light at frequencies or wavelengths characteristic of the element of interest (hence the name atomic absorption spectrometry).
This acquisition marked the beginning of the research and development of analytical systems in the area of atomic absorption spectrometry and molecular spectroscopy.
In molecular absorption spectrometry, the absorption cross section σ is expressed in terms of a linestrength, S, and an (area-normalized) lineshape function, Φ.
As the amounts of these chemical elements trapped in the flint are so small, it is necessary to use a sensitive analytical technique, namely atomic absorption spectrometry (see glossary).
Cavity-enhanced absorption spectrometry (CEAS)
The specific field of research is the measurement of atmospheric gases by infrared solar absorption spectrometry.
Laser absorption spectrometry (LAS) refers to techniques that use lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS).
The new technology being incorporated into the Wolfson Laboratories includes optical and scanning electron microscopy, atomic absorption spectrometry, laser particle size analysis, X-radiography and assorted microscopes.
