Learning objectives
The course, composed by theoretical lessons and individual practice training, is aimed at providing the basic notions for the qualitative and quantitative determination of substances of pharmaceutical interest. In particular, during the practical training attention will be focused on the qualitative analysis and quantitative determination of inorganic compounds of pharmaceutical interest.
