The teaching program comprises a theoretical part, which imparts a knowledge of the chemical and instrumental analytical techniques for quantitative measurement and determination of the purity of pharmaceutical substances. It is followed by an applied part, during which the notions learnt are put into practice. The chemical techniques include volumetric analyses realised by: acid and base neutralization, precipitimetric titrations, redox titrations, complexometric titrations. The instrumental techniques include quantitative analyses employing: potentiometry, spectroscopy (UV-VIS), analytical separations (GC, HPLC, CE). The applied part consists of 23 practical exercises of the European Pharmacopeia.
