Maggiori informazioni sul libro
High-resolution continuum source atomic absorption spectrometry (HR-CS AAS) represents a groundbreaking advancement since AAS's inception in 1955. This comprehensive discussion covers HR-CS AAS and its application to complex matrices, coinciding with the release of the first commercial instrument for this technique. It is essential for anyone interested in HR-CS AAS, particularly future users. The book highlights the advantages of HR-CS AAS over traditional line-source AAS through practical examples and numerous full-color figures. This new technique addresses significant limitations of established AAS, especially in accurate background measurement and correction. By utilizing a continuum radiation source and a CCD array detector, it enhances visibility in the spectral environment, aiding method development and reducing interferences. Designed as a supplement to the standard reference work on AAS, it does not reiterate basic principles but focuses on new information essential for leveraging HR-CS AAS. It includes characteristic concentration data for flame atomization and mass data for electrothermal atomization for all elements, along with secondary lines for higher analyte concentrations. Additionally, it presents highly resolved molecular absorption spectra of nitric, sulfuric, and phosphoric acids in an air-acetylene flame, illustrating potential spectral interferences alongside atomic lines.
