This thesis presents the main results of the studies developed during the PhD at the Instituto de Astronomia, Geofísica e Ciências Atmosféricas, of the Universidade de São Paulo, that resulted in four papers as the first author and one peer-reviewed proceeding. All papers are attached in Appendix A. The main interest throughout the PhD is to study the Formation and early Chemical Evolution of the Galaxy via precise chemical abundances of the metal-poor component of the Galactic inner halo. We explored the viability of a chemical analysis via line-by-line differential abundance analysis in low metallicity stars, and showed that the increased precision might reveal small differences and inhomogeneities that can not be seen in a regular spectr...
