Abstract: We present the results of our analysis of the vertical element stratification in the atmospheres of 9 roAp stars. Using high resolution observations (R≈100 000) obtained with the ESO-VLT spectrograph UVES and state of the art model atmosphere and spectral synthesis codes, we analysed the inhomogeneous vertical distribution of Mg, Si, Ca, Cr, Fe and Sr in 10 Aquilae (HD 176232) and Fe stratification in the whole sample. We present the derived vertical abundance map of 10 Aquilae's atmosphere and compare our findings with Fe stratification profiles of all roAp stars.
