Elemental abundance analysis are derived for the Mercury-Manganese star HR4817 (B8II/III), using CCD recorded exposures obtained with the EBASIM echelle spectrograph in the CASLEO (Complejo Astronómico El Leoncito) 2.1 m telescope in Argentina. The spectra coverage is 390-900 nm. The abundances and microturbulence are calculated using synthetic spectra. The results are compared with previous analyses made with spectra taken using the REOSC echelle spectrograph at CASLEO. With this method we make better determinations of abundances and microturbulence, and identify new chemical elements.
