Abstract

The spectrochemical analysis of a sample depends upon the facts that the frequencies of the lines in the spectrum indicate qualitative composition and the relative intensities of the lines are a function of its quantitative composition. The frequencies of the lines (or their wavelengths) are a fundamental property of the atoms involved and cannot be influenced to any great extent by the physical surroundings of the atom. However, the spectral line intensity of an element has been shown to be influenced by the other materials which make up the sample. This effect is known as the extraneous element effect, numerous reports of its existance have been made, and some studies have been undertaken to evaluate it. Because of the dependence of the observed intensity upon factors other than concentration alone, a more complete and thorough understanding of these effects becomes imperative for the further refinement and improvement of quantitative spectrochemical analysis.
