AbstractWe derive the full chemical enrichment histories for 3800 early-type galaxies, including both star forming and passively evolving systems. For this purpose we have developed a method to simultaneously derive the element abundance ratios [C/Fe], [N/Fe], [Mg/Fe], [Ca/Fe] and [Ti/Fe] for unresolved stellar populations. The method is based on up-to-date stellar population models with varying element abundance ratios. A novelty of the models is that they are flux-calibrated, removing the dependence on the Lick/IDS system. Trends with velocity dispersion are investigated where [Mg/Fe] and [C/Fe] are found to show very similar trends, while [N/Fe] show overall lower abundances ratios. [Ca/Fe] ratios are close to solar values over the velocity dispersion range covered. Tentative, due to large scatter, result for [Ti/Fe] implies that Ti follow the trends of Ca.
