Instrumentation. Atomic absorption spectrophotometers use the same single-beam or double-beam optics described earlier for molecular absorption spectrophotometers (see Figure and Figure ).There is, however, an important additional need in atomic absorption spectroscopy: we first must covert the analyte into free atoms.

History of atomic absorption spectroscopy. The earliest spectroscopy was first described by Marcus Marci von Kronland in by analyzing sunlight as is passed through water droplets and thus creating a rainbow. Atomic absorption spectrometry has been the most popular method for metal determination in general and the most widely used technique for analyses of trace elements in foods.

The popularity of this method arises from its analytical specificity, good detection limits, excellent precision, and relatively low cost. In Figure is shown an FIA manifold used in a theoretical hydrodynamic study involving the injection of a dye. At the bottom is the profile exhibited by the dye plug in its way from the injection point to the detector.

The result is an asymmetric peak (Figure (b)) exhibiting a χ 2 type height and area of the peak are proportional to the concentration of the target. Atomic Absorption Spectroscopy.

The main aim of this book is to cover all major topics which are required to equip scholars with the recent advancement in this field. The book is divided into 12 chapters with an emphasis on specific topics.

Kurt J. Irgolic, in Techniques and Instrumentation in Analytical Chemistry, HG-flame atomic absorption spectrometry. Although flame atomic absorption spectrometry is not well suited for the determination of total arsenic by direct aspiration of a liquid sample into the flame (Section ), this method does have detection limits of a few nanograms of arsenic when coupled.

Flow injection analysis (FIA) is an approach to chemical analysis. It is accomplished by injecting a plug of sample into a flowing carrier stream. FIA techniques developed into a wide array of applications using spectrophotometry, fluorescence spectroscopy, atomic absorption spectroscopy, mass spectrometry, and other methods of instrumental.

The concept of flow injection analysis (FIA) was introduced in the mid-seventies. It was preceded by the success of segmented flow analysis, mainly in clinical and environmental analysis.
