Atomic absorption spectrometry
1998This 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 ...

Atomic absorption spectrometry
Environmental Pollution, 1987The 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.

Fraunhofer Effect Atomic Absorption Spectrometry
Analytical Chemistry, 2005The 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
1970The 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 ...

Atomic absorption, atomic fluorescence, and flame emission spectrometry
Analytical Chemistry, 1988You don't know much and that's a fact. While this originates from Alice in Wonderland, it adequately describes the feeling at the end of a biennium when 2000+ articles are perused before compiling this review. During the last two years articles have appeared which solved problems that experience and history suggest never were a problem, while other ...
