Abstract
We present the more refined abundances of elements (C, O, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Zn, Sr, Y, Zr and Ba) determined using the computationally intensive ATLAS12 atmosphere model for the metallic-line stars Dra and HR 7545. We compare the chemical abundances derived from ATLAS9 model atmosphere with those of derived from ATLAS12. The abundances are in agreement with each other, within their uncertainties. We thus state that ATLAS9 may be used for the abundance analysis of slowly rotating chemically peculiar stars, such as Dra and HR 7545
