Abstract At present, a new scientific area in physical and chemical procedures of analysis, the metrology of analysis of substances and materials, has rapidly gained momentum. One of the main objectives of this research area is to obtain true information about the chemical composition of objects being analysed. Here under the correctness of an analysis we understand the quantity| Ĉ- C|. This quantity is used as a measure to establish the correspondence between the true element content C and its estimate Ĉ obtained from a series of measurements, where As the true element content serves its concentration determined in a standard sample. This defines the role attached to standard samples in such investigations. This paper presents some results of recent investigations carried out by the author and his co-workers in an attempt to solve the problem of obtaining standard reference materials (SRM) needed to test the correctness of and assess the techniques for spectral analysis of multicomponent substances and materials.
