TLDR
In this paper, the suppression of atomic excitation in a microwave-induced plasma due to the presence of sodium has been studied for three different nebulization systems and the results indicate that the sodium suppression effects observed can be largely accounted for by reductions in the analyte transport efficiency due to changes in the aerodynamic characteristics of the aerosol resulting from variations in the salt content of the nebulized solutions.Abstract:
The suppression of atomic excitation in a microwave-induced plasma due to the presence of sodium has been studied for three different nebulization systems. Evaluation of the factors affecting this effect has shown that its occurrence depends on the nature of the analytical aerosol introduced and the aerodynamic features of the sample nebulization system. The results indicate that the sodium suppression effects observed can be largely accounted for by reductions in the analyte transport efficiency due to changes in the aerodynamic characteristics of the aerosol resulting from variations in the salt content of the nebulized solutions. It is further shown that these effects may be generally predicted on the basis of fluid mechanical principles and that these may be used to design systems to eliminate the interferences. The study under-scores the essentiality of considering aerodynamic factors in formulating mechanistic explanations for interference effects in flames and plasmas.read more

Interference from easily ionizable element matrices in inductively coupled plasma emission spectrometry—a spatial study
M.W. Blades,Gary Horlick +1 more
TL;DR: In this article, the effect of easily ionizabie elements (EIE) on analyte emission in the inductively coupled plasma has been carried out, and significant spatial shifts, enhancements and depressions are induced by the presence of an EIE and limited fixed height measurements may be seriously misleading with respect to interpretation of the effects of ElEs.

Atomization problems in atomic absorption spectroscopy—I. A study of the operation of a typical nebulizer, spray chamber and burner system
TL;DR: In this article, a study of the mode of operation of the nebulizing system of a commercial atomic absorption spectrophotometer was made, and an experimental determination of drop-size distribution of the spray entering the flame points to the importance of small drop size for the efficient atomization of metals which tend to form refractory compounds in the flame.
