Course objectives
Objectives: To provide the theoretical and practical knowledge for qualitatively performing chemical and instrumental analysis of inorganic and organic substances including pharmaceuticals, emphasizing the importance of methods e.g. in drug analysis and in studying structural and physico-chemical properties of substances related to their biological effect. Emphasis is placed on shaping the logical thought processes of a pharmacist important for his future professional use. Practical exercises are required to master working habits and students' independent approach to solving analytical problems.
Learning outcomes
After completing the course the student will be able to: - understand the meaning and principles of classical and modern quantitative analytical chemistry - have an overview of methods and practically perform gravimetry, volumetry, photometry, potentiometric titration, HPLC and capillary electrophoresis
