PRACTICAL INTEREST OF MULTICOMPONENT STANDARDS FOR QUANTITATIVE AES

In this paper, it is first emphasized that the parameters of the class ic expression of the Auger signal can be grouped into three terms that are independent of each other: the first relative to recording condit ions, the second to an i-element Auger transition and the last to samp le chemistry. Consequently, it is shown that, using a relevant multico mponent standard set, it is possible to free quantitative AES of alloy s from experimental conditions. The set of standards has to contain al l the elements of the sample; each standard has to contain at least on e element of the sample and one element common with another standard. By using the described method, a library of multicomponent standard sp ectra can be created, which can easily be used by other laboratories.
