Some further examples may be found listed in the useful monograph on spectrochemical analysis by Lajunen. They do not present a problem as long as the analyst is aware of their existence. They may be circumvented by using a different spectral wavelength. Most of the above examples do not in fact occur at the wavelength corresponding to the best sensitivity. At high concentrations especially, a number of elements produce significant concentrations of polyatomic species in flames.
When comparing sources, the absorbance signal size and stability for a suitable dilute standard solution should be compared, with all other conditions carefully optimized, and not just the lamp intensities and stabilities. The most intense lamp may not be the one which gives the greatest signal or signal-to-noise ratio. Atomizer-related Parameters Choice of Atomizer We have already seen in Chapter 2 that choice of atomizer system to be used may have a dramatic effect upon sensitivity, and thus upon signal-to-noise ratio.
References 41 and 42). 41 The resulting interferences were so severe that they soon fell out of favour, and must now be regarded as being of academic interest only. D. J. Vickers, Anal. , 1964, 36, 161. S. S. West, Anal. Chim. Acta, 1970, 50, 5 . CHAPTER 3 Interferences and How to Overcome T h e m From Chapters 1 and 2, it should be clear that flame AAS and AFS, and FES are all secondary analytical techniques which depend upon a comparison of signals from samples with those from standards. To yield accurate results, it is imperative in all three techniques that the determinant in samples and standards behaves in exactly the same way.
