Flame Photometry, Atomic Absorption, and Inductively Coupled Plasmas

Consequently light is absorbed by a ground state atom or emittedby an excited atom at very precise wavelengths, resulting in line spectra. For example, the cure of anaerobic adhesives on nonreactive surfaces is usually assisted by the use of an active metal-based primer. August 15, by Ranga. However, occasional problems may arise But because of interferences, poor reproducibility, and poor detection limits an alternative method for some elements--mostly metalloids--has been devel-oped. These can be divided into the broad categories of biological analysis, environmental and marine analysis, and geological analysis.

Flame Photometric Analysis with Wavelength Shift Using AA-7000

Smith, C. The new technique of atomic absorption spectrometry has already achieved some interesting applications to the analytical problems of the petroleum industry. In combining some of the desirable characteristics of optical emission spectrography, flame photometry, and spectrophotometry, this new tool provides fast, sensitive, and precise analytical results. In briefly describing methods for the determination of trace metals in gas oils, gasolines, new and used lubricating oils, and other petroleum products, the present scope and limitations of atomic absorption will be evaluated. The performance of a new multichannel spectrometer will be described. This new instrument can determine up to 12 elements simultaneously in less than 15 seconds.


Atomic emission spectrometry, flame photometry, and atomic absorption spectrometry are analytical techniques that measure the concentration of chemical.


Applied Spectroscopy

AAS is a single-element method used for trace metal analysis of e. Spectroscopic determination of atomic species can only be performed on a gasified sample in which the individual atoms such as Ag, Al, Au, Fe and Mg are well-seperated from each other.
