Flame Atomic Absorption Spectroscopy
•Flame Atomic Absorption is a very common technique for detecting metals present in samples.
•The technique is based on the principle that ground state metals absorb light at a
•Metal ions in a solution are converted to atomic state by means of a flame.
•When light of the correct wavelength is supplied, the amount of light absorbed is measured and
a reading for concentration can be obtained.
•Flame atomic absorption is a very accurate quantitative technique and also a good qualitative
•This is one of the main reasons it is the most widely used of the atomic absorption methods.
Flame atomic absorption spectroscopy (FAAS) is suitable for measurement of a limited range of elements present at concentrations greater than approximately 1μgml−1 in biological fluids, and for the analysis of solutions obtained from biological tissues at the completion of the sample preparation steps.
