High-resolution continuum source atomic absorption spectrometry (HR-CS AAS)
is the most revolutionary innovation since the introduction of AAS in 1955.
Here, the authors provide the first complete and comprehensive discussion of
HR-CS AAS and its application to the analysis of a variety of difficult
matrices. Published just in time with the first commercial instrument available
for this new technique, the book is a must for all those who want to know more
about HR-CS AAS, and in particular for all future users.
High-Resolution Continuum Source AAS: The Better Way to Do Atomic Absorption Spectrometry
The advantages of the new technique over conventional line-source AAS are
clearly demonstrated using practical examples and numerous figures, many in full
color. HR-CS AAS is overcoming essentially all the remaining limitations of
established AAS, particularly the notorious problem of accurate background
measurement and correction. Using a continuum radiation source and a CCD array
detector makes the spectral environment visible to several tenths of a nanometer
on both sides of the analytical line, tremendously facilitating method
development and elimination of interferences.
Conceived as a supplement to the standard reference work on AAS by B. Welz
and M. Sperling, this book does not repeat such fundamentals as the principles
of atomizers or atomization mechanisms. Instead, it is strictly focused on new
and additional information required to profit from HR-CS AAS. It presents
characteristic concentration for flame atomization and characteristic mass data
for electrothermal atomization for all elements, as well as listing numerous
secondary lines of lower sensitivity for the determination of higher analyte
concentrations. The highly resolved molecular absorption spectra of nitric,
sulfuric and phosphoric acids, observed in an air-acetylene flame, which are
depicted together with the atomic lines of all elements, make it possible to
predict potential spectral interferences.
