Using the analysis of the elastic lines distortions of the diffraction spectra with the involvement of the high order central moments of the distribution, the sensitivity of the developed technique to the presence of an admixture of a bulk component in nanocomposite materials was estimated. Cases for the main types of instrumental resolution functions of diffractometers and functions describing the response from materials embedded in the pore space of nanomatrices such as SBA-15, MCM-41, MCM-48, etc. are considered. Keywords: porous matrices, diffraction, resolution function, nanocomposite materials, elastic peak line shape, higher central moments of distribution.
