Atomic absorption spectrometry

Environmental Pollution, 1987
The phenomenon of atomic absorption has been known for a long time. As early as the first quarter of the nineteenth century, Wollaston and Fraunhofer observed lines in the spectrum of the Sun now known to be caused by the absorption of light by atomic vapour in the Sun’s atmosphere.

Atomic absorption spectrometry

1998
This chapter is aimed at the reader who has only a basic knowledge of the technique (some basic undergraduate course of instrumental analysis) and no real experience in using the method. Theory, descriptions of the instruments and methods of analysis will be described, mainly paying attention to the implications for experimental work, so that the ...

Fraunhofer Effect Atomic Absorption Spectrometry

Analytical Chemistry, 2005
The dark lines in the solar spectrum were discovered by Wollaston and cataloged by Fraunhofer in the early days of the 19th century. Some years later, Kirchhoff explained the appearance of the dark lines: the sun was acting as a continuum light source and metals in the ground state in its atmosphere were absorbing characteristic narrow regions of the ...

Atomic Absorption Spectrometry

1970
The first application of atomic absorption spectra to chemical analysis was made over 100 years ago by Kirchhoff [1], who demonstrated the presence of various elements in the solar atmosphere. Together with Bunsen he demonstrated shortly afterwards that atomic spectra, whether in emission or absorption, could be the basis of a powerful method of ...

Zeeman atomic absorption spectrometry

TrAC Trends in Analytical Chemistry, 1982
Abstract The shift of atomic spectral lines in a magnetic field (the Zeeman effect) forms the basis for three novel developments in atomic absorption spectrometry: (i) greatly improved background correction; (ii) the use of forward scattering techniques as an analytical tool; (iii) the determination of small gaseous molecules.
