Abstract: A review of the recent results on abundance and stratification analysis of the magnetic CP stars is presented. It includes a brief description of the methods as well as a comparison between the element distributions derived from observations and provided by the self-consistent diffusion model atmosphere calculations. He and Ca isotopic separation in the atmospheres of CP stars is considered. The importance of stratification analysis for the study of pulsations in roAp atmospheres is emphasized. Finally, I briefly discuss the recently published identification of unstable elements in spectra of Przybylski's star (HD 101065).
