Modern instrumental methods used to determine the composition, microstructure and surface structure should respond to increasingly complex problems material testing requirements, in order to meet the increasingly strict technical conditions of receiving and using materials, and therefore the delivery of the finished product. In the aviation industry, with regard to the chemical composition of materials, the requirements have been extended to a significantly larger number of parameters: to "impurities", to trace elements, to micro alloying components, to local, as well as to structural and phase analysis. In this sense, requirements such as: accuracy of determination; determination of low concentrations (traces); duration of the analysis; simultaneous determination of a number of elements under the same experimental conditions; microanalysis (below 1 micron), i.e. testing at small locations are inviolable.
